A great teacher. Extremely organized and helpful

His lecture is very organized and he is very helpful during office hours. He offers plenty of sample exams online which made your study easier.

Great Professor! Helpful and organized

Great professor, but english is not his first language so it takes awhile to catch on. Tests are fair and very similar to the practice tests.

He is a good professor and it is not difficult to do well if you pay attention and take good notes in class, do the suggested practice problems and the practice exams. Textbook reading is not required to do well. Exams are very similar to practice tests.

His lecture is very organized and he is extremely helpful during office hours. He offers plenty of sample exams online which made your study easier.

I really really liked having professor liu. Obviously isn't english, but he follows his power points so its pretty easy to figure out what he is saying. He's very organized and gives a good idea of what will be on the exam w practice exams. Do the practice problems, pay attention in class, and go to his office hours and you'll do well!

Prof. Liu is a gem. Take him if you can. He is your man for Ochem1 at Pitt.

Professor Liu is a great teacher both inside and outside the classroom. I really developed a deep appreciation of his teaching style particularly after taking Chem0320 class with another professor in the chemistry department.

Prof. Liu is an effective lecturer. His notes are organized and easy to follow. His exams are straightforward and he curved generously. He allocates 20% of your overall grade to the homework and class participation. It is quite easy to get a good grade with him if you engage actively.

His midterms were very easy and straightforward. No tricks. Just read his notes+textbook and youll be fine. practice exams are nearly identical to the test. His final was surprisingly brutal though. But he makes 85 an A so just do well on midterms and decent on the final. Was a blessing compared to other orgo2 profs in the dept.

I'm terrible at chem and managed to get an A in this class. Notes aren't the best, but Liu gives credit for homework and participation which is uncommon. The homework can be really hard and he always put a random 1/2 homework q's on the midterms. I recommend meeting with him after tests and he'll pinpoint how you can improve!

Traditionally Ochem is a hard class, but his way of lecturing helps reducing the difficulty a lot. He always explained the detailed machnism of different rxns, and help linking and comparing similar rxns, which really helps to remember and understand complexing rxns. Hes also really patient and esay to reach outside of class.

XL is a professor who truly wants his students to understand ochem information and be able to apply it to be able to predict how reactions take place. He talks to his students in a non-pretentious way and is very approachable and acomodating with office hours. His recitation immediately following lecture helps to solidify concepts you are learning

I would take Ochem 2 with Dr. Xinyu because he helps you past the course and he knows that you are only trying to take the course to graduate or to to med school. He is very willing to help you when you need it. His tests are manageable and he has a nice curve. Study the lecture notes, look over the previous exam, read the textbook to do well.

Dr. Liu is a great professor, however his exams are definitely more difficult than he originally implies. As long as you do the recommended book problems and the homework you will do well.

Every chapter in this class has a sapling homework assignment that is 19-21 questions long, but they are helpful for actually learning the material. There are only certain problem types on his exams (such as mechanistic or synthesis problems) in which he gives partial credit for. Go to office hours for help, do practice problems, make flashcards.

It can sometimes be difficult to understand him a little, but he is very nice and will answer any question or provide clarification if needed.

Dr. Liu is an organized lecturer. He breaks down all of the material from the book in a digestible way and is helpful and friendly. He allocates 20% of your grade to participation and homework, which is generous, but his tests aren't that bad either. Definitely make a list of the reactions/mechanisms and write them out, read, and go over Sapling.

Xinyu Liu is a very straightforward instructor and covers only what will be tested on. The exams are challenging but test your knowledge on the subjects covered in lecture. He is nice and makes jokes to help keep the mood light hearted. He includes Sapling homework which I think was very helpful and made me start learning the material early.

I view XL as a very good and fair instructor especially compared to some others I have had in the past. Maybe if you are hard of hearing or not the best listener he would not be the best choice as he is occasionally hard to understand. Although overall, I think that point is overblown by some people.

XL is a pretty good instructor. He is patient while explaining things and takes the time to reexplain if you don't understand it the first time. He lets you drop a midterm, and has Sapling questions. His lecture time was 6-7:15 for me which I didn't like, but still worth taking him. You need to work hard if you want to do well, go to office hours!

Professor Liu is also a good professor and a good person, but his lectures can be dry and not engaging at times. He does care about his students and wants them to succeed, but you definitely have to work in this class. Exams are fair and he does give online homework to help boost grades.

Good instructors Ive had state their expectations and stick to them & the syllabus schedule. The ineffective ones are disorganized and it's difficult to prepare for class. Prof Liu is an effective instructor who is organized and provides sample exams so you get a feel for what to know on an exam.

XL is good at providing many helpful study tools like chapter review summaries, guided lecture notes, and graded homework. Exams are straightforward and reflect concepts learned in class, but there is no partial credit.

Professor Liu provides plenty of opportunities for help and practice if they are needed. He does not purposefully try to confuse us. He did not only have exams that determined our grades. He provided other opportunities for success as well. People should ask about the materials provided in the class as well as the format of the class itself.

Dr. Liu is a good choice for OChem2. He is definitely not easy, but is also manageable. The online homeworks were not really relevant to the exams, but the optional book problems he assigns were better. You must buy a subscription to masterorganicchemistry, it helps SO much with his class. His exams are brutal on partial credit, but he curves.

He uploads all lecture notes, so you don't need to attend class to pass. Homework assignments are a nice grade boost. Lecture notes aren't the best, I read the textbook before exams. He always provides a practice exam. Doesn't give much partial credit on the exams, but he drops an exam which is nice. I also have heard he gives a nice curve.

XL is a great instructor. The way he presents the notes to the class with the print outs is very effective, and very easy for you to retain it. He has a nice pace to the class with each chapter being the same amount of time. The recitation is structured very well.

Prof. Liu is a good choice for ochem 2. His exams are fair. He posts a practice exam before that is usually similar to the format of the exam you will get. He does Sapling which is rare for OChem and extremely helpful for your grade. He is brutal with partial credit though.

Professor Liu is a solid choice for Organic Chemistry 2 and I thoroughly enjoyed his class. His exams are extremely fair and you can do well if you study his notes in great detail and learn the assigned Sapling Homework. His notes are very messy so be sure to attend class so you can make them neat and understand his scribbling. Overall, Liu is info

I still feel that Dr. Liu is a fair teacher and helps to understand the the mechanisms and such. In order to succeed, coming to class and paying attention is definitely number one. The next most important thing is to do and understand the Sapling and the practice exam Dr. Liu gives and any prospective student should be fine.

Xinyu is a good bet for OChem2. His exams are straightforward (but little partial credit) and his recitations are optional (and pretty useless). He posts lecture notes online; make sure to fully understand them to ace the exams. He gives practice exams too. Homework also counts as part of grade. Boring Lecturer, but covers all that you need.

I have Xinyu Liu as my Ochem2 instructor. Professor Liu is a very good professor for teaching this class. Notes and explanations are very clear throughout the entire semester. However, his test is a little bit challenging because there is a lot of application of the knowledge learned instead of just writing reaction.

Well what I like about Professor Liu is that he is very knowledgeable (and can fluidly present material), and that he is not math-focused. I am not bad at the math part, but I'd much rather know the theory and have the math fall into place later. If you share this belief, I would recommend you to this professors.

In comparison to other instructors I've had, XL is one of the better ones. He gives printed out fill-in notes which make studying easier. Sapling points and dropping a midterm is something he does that other ochem2 professors don't. Exams are tough, but manageable if you study sapling, book problems, and the past exams that he uploads.

Dr. Liu is very passionate in helping students succeed. If you go to his office hours, its very helpful to clarify on anything that you dont understand. His tests are fair and are based on his lectures which are based on the textbook so if you know the book or his lectures, you will do well on his tests.

I did not have a choice really on who I took for Orgo1/2. OChem will require a LOT of outside work no matter how good your professor is. Go to all lectures, do all offered homework, find people in the class to work with, actually read the textbook, outline the reactions in a separate notebook and include what contexts change them.

XL handwrites his notes on the projector as he goes which is very helpful. He has sapling grades, allows a dropped grade, and is available for outside help. His recitations are not that helpful, but lectures are very good. Doing practice problems will help you do well in this course. He is always there to offer help if needed.

Dr. Liu's lectures are very good and straight forward. He is organized and his exams are fair. While you'll have to work to do well in the course, you are given enough resources to succeed. I highly recommend to start studying a week in advance and make sure you really know everything he teaches in class. Book problems and sample midterm help a lot

Familiarize yourself with trends, theories, and mechanism. They appear on the exams in more detail. Good instructor but a lot of work must come from you in order to succeed. Understanding the book problems and sapling will help and using joechem is also useful.

Dr. Liu's lecture is clear and easy to follow. If you understand the mechanism and the examples he taught, you will be fine on the exam. He is accessible outside class. If you go to his office hour, he explains question in details very well, and it is really helpful.

Dr. Liu is good professor for Ochem 2. The class is fast-paced, but he gives very clear guidelines on what is expected of us, as well as plenty of practice through Sapling homework problems and practice exams. Ochem is difficult and can be dull, but make an effort (read the book, study) and you will do well in his class.

Lectures are run utilizing empty note packets that are handed out to fill in during class and recitation had practice quiz questions given and explained. Lowest of three midterms is dropped. Sapling and participation in surveys is also a percentage of the final grade.

The class was not as engaging as some professors teach. However, the class was taught well and has provided a thorough learning of the class. The exams are also straightforward and are a fair assessment of your capability in the class. Regardless of who you take for organic chemistry, the course is difficult and requires a lot of studying.

He is an organized lecturer, provides notes after each lecture & posts practice exams that prepare you well for the exams. He drops 1 exam and you get 4 tries with no penalty on the homework so you can actually try the problems. To succeed in this class you definitely have to keep up with the lectures because its a lot of material, but thats Ochem!

Xinyu was a great instructor in my opinion. His guided notes make his lectures easy to follow and he usually does not waste too much time on in-depth concepts that are irrelevant to exams. He mostly focuses on giving you the information you need to succeed in the course and nothing more. Choosing the right session is based on your own preference.

XL creates notes to fill out during class. These notes are structured out to separate the key concepts of the chapter, this is very helpful. XL has great pacing which will allow our section to finish on time without rushing to finish in the last class. The best way to succeed is to review as much as you can in small spurts throughout the semester

Prof. Xinyu Liu is an extremely will organized professor who sets reasonable expectations for his students and is effectively able to teach Organic Chemistry 2 (keeping in mind the difficulty of the material). His provided lecture notes are very helpful for note taking and studying, and the provided practice midterms are a great for exam review.

Xinyu Liu was a great choice because he gives you all the resources you need to do well in the class. He is a great lecturer and recitations were helpful, Sapling homework was similar to exams, and class notes were fairly organized. Exams reflected the material he taught well. Overall a great choice for OChem 2.

I like Prof. Lius teaching style; he is humorous, approachable, and knowledgeable. When selecting a professor, take other peoples opinions with a grain of salt. Tips for success: mastering 20 problems is better than semi-mastering 40 problems, review lecture notes daily, go into the course with confidence (not a mindset of failure). Good luck!

XL is a great instructor. He offers a great deal of time to help students outside of class. His exams are fair in comparison to other professors. XL posts midterm study guides which are extremely helpful when preparing for exams, and he offers regrades. Sapling helps boost your grade in the class, and they are good practice to understand key topics

I think Dr. Liu is a good instructor for OChem 2. he gives practice exams for each exam, which is really helpful. Right before exams, he always extends his office hours, which shows he cares about the success of his students. Overall, if you read the textbook, take lecture notes, do practice problems, you can do well in this class.

Dr. Liu has been a great instructor. I really enjoy his teaching style and I appreciate having the notes uploaded on course web. Dr. Liu also provides a lot of office hours. He is also very attentive and listens to what the students feel needs to be adjusted for everyone to receive the most out of their education.

If you are taking XL for organic chemistry 2, it is very easy to succeed, he provides all materials necessary to study for the exams, and presents it in a way that diminishes any confusion. Also, XL is very fair in that you are allowed to drop a midterm grade, and that your homework counts as part of the grade, which is a big booster. Overall great

Dr. Liu is a very fair professor. He wants you to do well in the class. He provides many opportunities for success, including Sapling, practice midterms, office hours, study guides, recitation worksheets, and uploading his notes online. I like his lectures, but sometimes I have to read the textbook to truly understand concepts. His exams are fair.

Having Dr. Liu as my OChem2 professor has been a positive experience overall. He assigns sapling homework that counts towards your final grade for the class. He posts all of his notes on courseweb as well as practice midterms and study guides. The best way to succeed is to do all of the sapling homework and practice midterms.

Xinyu is great. He does have an accent but it's not too bad. He posts a lot of materials online like class notes, as well as recitation summaries and practice exams. He also gives out quite a bit of homework but it's SO worth it because it helps you grasp the subject and you get a lot of extra "Free points"

Lets you drop your lowest exam grade

Professor Liu's exams are pretty doable as long as you've been keeping up the whole semester. You can't just skate by just from going to lecture. You have to make sure you're doing the homework consistently and keeping up with the material. Compared to other Ochem 2 professors, I'd say Professor Liu is not a bad choice.

Exams are similar level to OChem1 exams, and he gives practice problems. Lectures are dry, but he puts all notes online. You get to drop your lowest exam grade, which is nice and averages have been fairly low. You need to put in a lot of work outside of class and read the book. Sapling hw is easy 100% for that part of grade.

XL first is a great person. He is easily approached and very fair in regard to exam difficulty. His lectures are usually organized, but some out of the classroom studying is necessary. I would recommend XL to anyone who likes to be independent with their studies.

Professor Liu is a wonderful professor that I have ever met in Upitt. I really like his teaching style, he let us take down the notes that help us to remember and focus on the class. His exam is really like his practice exam, and you can drop one of three exams which makes this class easier to pass.

My Organic Chemistry 1 professor was Professor Nelson. I liked his pre-made notes. Professor Liu is very knowledgeable, but sometimes I get lost due to the speed with which he writes the notes, as they aren't pre-prepared. Both professors had clear expectations and graded with similar standards, but Liu goes much faster in lecture.

Dr. Liu has been a good lecturer. First, both his class and his CourseWeb page are very organized which allows me to follow along with the class more easily and his notes are online. Second, he focuses mostly on what is important to know and gives plenty of examples to help me understand the reactions.

As an OChem 2 professor, Prof. Liu was very thorough in explanations. OChem as a subject is fairly challenging, but he drops the lowest of three midterm scores, which gives you a chance to learn how he tests and what he emphasizes. He offers many practice problems to help you succeed, and is open to office hours to discuss where you need to focus.

Prof Liu is a very nice and extremely intelligent man. His teaching style worked well for me by having unfilled lecture notes in a very structured way. His tests are fair for the most part and there are rarely surprises. The sapling homework helped make me stay on top of the work and study throughout the course. Tough class but a good prof to take.

Professor Xinyu Liu is very knowledgeable, and his lectures are very organized. However, I have found his exams to be pretty tough. Make sure to look over the old exams that he posts to help identify your problem areas. Also, take advantage of the extra sapling assignments, because those questions are similar to some of the exam questions.

XL is an excellent professor. He has succinct course outlines and posts copies of his lectures online for you to review. His recitations offer opportunities for you to practice problem solving skills with the applicaiton of the theories learned in class. He makes it a point to offer office hours and they are very helpful if you prepare for them.

This ochem 2 class is a much different experience than my ochem 1 class. While my ochem 1 class was interactive and a mix of examples and explanations, this class is not interactive at all and is focused mainly on examples. Xinyu is a good professor and does a pretty good job explaining the topics. The only real problems I have are that sometimes

Professor Liu is very accessible outside of class. His lectures are dense, but he uses two separate projectors and an outline as well, so keeping up is not usually an issue. If you are slower to write, he is more than happy to help you fill in what you missed. No complaints. Harsh grader.

Professor Liu is a solid choice for OChem2. Lots of positives: Sapling hw for credit, practice exams, very approachable in office hours, exams reflects covered material, 1 dropped exam. Only complaints would be the speed of the lectures, which can make them hard to follow and limit more understanding, and lack of partial credit on exams.

XL is a great professor who explains things in details and make connections among concepts and materials. He is friendly and witty in office hours. Although, his accent could be difficult to understand, his notes are well-detailed and he also provides more detailed explanations in his office hours. XL focuses on the learning of the materials, and i

XL is good professor who is clear and organized. He outlines the class policies correctly and fairly and while exams are quite challenging, much of it is due to the nature of the subject. His class policies are fair and while his accent poses a challenge, it is by no means a major deterring factor. I would recommend taking him.

Xinyu Liu is also a good professor. He teaches well and is extremely organized. His exams test the material taught but also require you to make your own inferences based on what was taught in class. His sapling assignments are also very beneficial to help understand the material. I would recommend choosing the session based teacher quality.

Dr. Lui gives his students many opportunities to do well in his class. One midterm is dropped and he offers extra credit. His exams are extremely similar to the ones he uploads as practice so studying those is a must. You can be very successful in this class if you stay on top of everything.

XL is a great professor. He does not want to see you fail. Your grade is based on exams, participation, and sapling so one bad grade won't kill you. You also get to drop one exam, so the class is feasible. Stay on top of lectures and you should be fine.

Undergraduates at Pitt severely over stress and over think organic chemistry. It's a difficult subject, but people make it out to be much more difficult than it actually is. In the end, you should pick a time slot that works well in your schedule. If you know you aren't a morning person don't take an 8AM. If you work during the day then you should

Professor Liu was a fair professor who clearly presented the information needed. Lectures are organized and follow the textbook. He posts his lecture notes online. Sapling homework and participation are worth one exam grade, and you are also allowed to drop an exam. Exams are fair. If you do all of the given practice problems, you should do well.

Solid choice for an Organic professor. Lectures are clear and detailed and really cares about student's inputs. Is pretty upfront about what's to be expected and exactly what you should expect. Sometimes in recitations he'll say something that ought to be on the exam so I'd suggest attending

XL's exams are very fair and he does a good job of covering all the material in class. However, the lectures are very dense and he moves fast so it is difficult for me to retain information during the lecture so I do a lot of learning outside of class. His exams are fair and sapling is worth an exam grade. You get to drop your worst exam.

Professor Liu is a great professor, who puts in a lot of time to help his students achieve. His lectures were very fast-paced, but material was clearly put. He provides all in-class material online, and he provides a sample exam that mirrors the format of the actual exam. His exams were difficult, but fair. I suggest going to his office hours.

For Ochem 2 I had Lui which was a better fit for me. The notes were more organized and I like categories. Going to recitation was not mandatory but they were a good supplement to the material in lecture. The textbook was also really helpful supplement to feel in blanks in the notes which I appreciated. Recitation summarizes are helpful also.

Professor Liu is good at rationalizing and teaching classes. He offers very organized and comprehensive lecture notes that help us understand the lecture better and review for the exams, the handouts are even better than ppts.

XL is a good professor. His exams a hard, but I suppose they are fair, especially considering he provides practice exams. His lectures are detailed, which is nice, but they are sometimes organized in confusing ways. I feel that the recitations made me more confused and I didn't always understand how they relate to the lectures.

Prof Liu cares for his students and has very fair exams. He provides the information he wants you to know, and presents it in a good way. He goes slightly fast sometimes, but there is a large amount of information to cover within the semester.

XL is a very fair instructor. He details exactly what he expects you to know, and there are no suprises on the exam . His homework and participation grades give a nice cushion to your grades. His notes and the sapling HW are the biggest resources for studying for his class. Also, know the starting material for given for a given product.

Dr. Liu is a very straightforward lecturer. He teaches mostly through generalized concepts and his exams follow a predictable format. He reviews the critical parts of Ochem 1 in Ochem 2 and I found I did not to review much to understand what was going on in class. His accent can be hard to understand initially.

I think Xinyu Liu is a great professor who creates great lecture notes as well as course materials as well as provides applicable and interesting examples of the application of OChem2 knowledge. However, the classes are not as interactive as they could be due to the inability for us to ask questions or answer proposed OChem2 problems.

He is concise and to the point, which is nice. If you can handle it, I think that having the class only twice as opposed to three times a week is very preferable. I also think that the grades are calculated fairly, with some participation and homework points. By studying and doing all of the outside work, I think a good grade is achievable.

I believe that XL genuinely wants his students to succeed. He provides many Sapling problems that are extremely helpful. Lecture can move at a fast pace because the class is naturally fast paced; however, XL provides streamlined notes to help focus. I chose XL because a friend within my major recommended him and said he would prepare me well.

Xinyu Liu provided a ton of materials and resources for the class, which are absolutely necessary when trying to learn organic chemistry. If you don't pay attention to his chapter summaries, lectures, and recitations then you will not do well in the class.

Professor Liu is a great professor. He cares about students' opinions and wants us to succeed in his class. Make sure you understand the concepts and mechanisms for every sapling and practice exam questions, then you will do great on his exams.

I think that XL is a good professor. He is very clear with his expectations and clearly explains what students need to do to succeed. Also, his exams are fair and always based off what we learn during lecture. However, students have to be prepared to put in the effort outside of class to read the textbook and complete the Sapling homework.

XL is also a very good professor. He brings more structure and organization to the class which is and outlines well what to expect from the course. The only downside to his teaching is that he does not give partial credit. This can be very frustrating on exams when a simple mistake costs you all points on a question. Make sure to do the sapling!

Dr. X. Liu is a good instructor. I really enjoy the teaching style of having an empty packet and being able to fill in the notes as he is teaching us the material. Your grade is heavily exam based but you are also graded on Sapling and participation via surveys.

I think he's a very solid choice for Ochem2. He keeps things simple, very organized, and condensed. Teaches the stuff you need to know for the exams. Sapling HW and indicated textbook problems are similar to exam problems (when it comes to style and concepts).

The professor is fair and honest. His notes are easy to follow and uploaded to courseweb promptly after every lecture, but the explanations given in class make it worth it to attend. The midterms are fair and can easily be passed with good preparation, but cramming won't help.

He is a very caring professor and you can tell he definitely wants his students to succeed. However, the class grading definitely relies heavily on the tests which can be pretty difficult. As long as you put in the time outside of class and don't procrastinate, you should be fine.

XL has been a great instructor. His notes are very straight forward and clear. I very much enjoy the application that he brings into the course, giving us examples of molecules that we use in our everyday life and how they are derived from organic chemistry. To do well in this section it is pretty simple, pay attention in class, attend recitation a

Dr. Liu moves fast through lectures, but good notes make for easier review. Exams are fair and are consistent with the Sapling homework, but there's no partial credit. Grades factor in participation, homework, and you get to drop your lowest exam grade. Overall, Ochem 2 is a difficult course in itself... be prepared to put in a lot of work.

Dr. Liu moves quickly through lectures but provides direct theory reasons along with ex. and he posts lecture notes online. His exams are difficult but fair but there is very little partial credit. Grades include 3 midterms, a final, and sapling hw. The lowest midterm grade is dropped. It is a difficult course but doable if you do the work.

Dr Liu is a great professor who is easy to follow in leacture. He provides empty slide to fill in with him as the class proceeds. He provides online homework(20% of your grade; same as exams). He only counts two of your three exams for a total of 40% of grade. His assigned homework is a strong representive of his chosen exam questions.

For OChem 2 I had XL; he was a pretty good professor. He provides fillable lecture notes and then he posts the fills notes online. Part of your grade is sapling, which helps your grade and the copies are good for exam review. His exams aren't super difficult, but he doesn't give partial credit on everything, which can really hurt your grade.

Professor Liu is a very capable and knowledgeable instructor that I would recommend to new students. I like that his lectures are very well constructed and organized and that he provides fillable notes that exactly correspond with the information that he is writing as he teaches. Also, the tests are fair and you'll have more than enough time.

XL is organized and has a set schedule with fair and properly length tests as well paced lectures for Orgo 2. The course structure set in place by XL helps students out as you are able to earn a test grade from homework as well as drop a test. In terms of studying for tests, I would encourage students to do textbook problems, and practice tests.

Dr. Lui is very well organized and shows how each chapter is connected throughout the class so you can easily follow along and see how each reaction and it's mechanisms are related. Do the practice tests he posts online and keep up with the online homework and you will be fine. He's also very helpful during office hours

He is a great instructor

Professor Liu is extremely fair. His tests reflect what he emphasizes on as important and he provides a laid out schedule for the whole semester. His test are challenging because there is barely any partial credit so missing a few questions plummets your test score. He makes up for this by allotting 20% of the grade to be from homework

XL is a great professor! He has notes online that are already structured for the class, so all you need to do is print them out and fill in the blank spaces while he is lecturing. He fills in a copy on the projector and posts it online, so it is easy to follow along and you can still get the notes if you are late to class or miss a class due to an

The class is challenging but that is expected in an Organic chemistry class. Overall He is a good professor and I found lectures to be long, but helpful. All the assignments are posted clearly and breakdowns for each chapter are provided. His class is designed well and he takes into account the feedback he receives on surveys.

Organic Chemistry 2 in general is hard. However, Dr. Liu makes gives organized and thorough notes to guide you through. It is important to study outside of class as frequently as possible, so tests will be easier. There will usually be one really challenging question on each test, but look through the pages before, it's usually the same concept.

In my opinion, I believe XLs methodology is one of the better ones I have seen in University of Pittsburgh. One of the main reasons that I live XLs methodology is the homework policy. Having four free tries before penalty allow me to practice stress free. One of my previous professors had a 20% penalty for each try.

Dr. Liu is quite personable. The exams are comprehensive, but there are not many opportunities to get points or partial credit, which really adds up over time. At times he overestimates his student's ability to retain information from organic chemistry 1 and the homework is very hard. Have your notes, textbook, and computer ready.

I had Professor Liu for OChem 2 and really enjoyed his teaching style. He has fillable packets and is easy to follow in class. The material is challenging but Liu has a lot of office hours and teaches the recitation himself, so he's accessible for questions. There's sapling homework too that's extremely helpful in learning the material.

I think XL is a very competent and effective professor. he conveys the information clearly and works very well Courseweb to ensure that the information is repeated and supported in multiple formats. his exams are as expected for the information conveyed in the lecture, the practice problems, and the sample exams reflect the exam well.

Dr. Lou was a very good professor and his class is very doable for Ochem. He is extremely fair and makes himself extremely accessible outside of class. He makes sure to provide numerous opportunities outside of lecture for you to learn to material and gives homework and participation grade. He is a great lecturer and post notes online.

Dr. Lius organization and availability outside the classroom allow students to succeed in his class. He offers homework in addition to dropping your lowest midterm. If you focus on studying the notes given in class and have thoroughly understood that material, it is almost completely unnecessary to read the text book.

3 midterms worth 40% grade (drop lowest), surveys + sapling 20%, final exam 40%. Midterms are very straightforward so know mechanisms and reactions and youll be fine. Final is impossible level, so ace the midterms as he curves the class. Recitations are optional and pointless. He uploads lecture slides online and is very caring. Good pick for Orgo

Dr. Liu is a great lecturer, but he covers way more information than he expects you to know, leaving you more than a little lost when trying to figure out what to study. His homeworks are a lot like his exams, which is good because he does not give out practice exams. TL;DR Liu is a good prof, but could be better.
