He's the lab teacher. He's very easy, lets you work in groups. He just signs off the labs and doesn't really see if you actually finished the lab, but you turn in the lab write ups. He's a nice guy.
Great teacher. Always abailable to help his students. Makes sure that sudents understand material. Great personality and awsome teacher. Gives opportunities to make up points that youve missed. The grade i give this teacher is an A+

if you want to changlle your future ,take him
He is a very nice guy,and very mercy when student is sick . He has patient to answer any questions. Class is clear ,but you have to work hard if you want to get A in this class.
has the asian accent and talks quickly. goes over material on tests before it is given. tests are not necessarily hard, but tricky, be sure to read the question carefully or else you will miss out on easy points.
Jimmy seems like a cool guy. I took this class over the summer (NOT recommended, it is hard!), but I'm sure over the regular, non-compressed semester it's better.He went fast, but then again I had an 8-week summer course.It's CHALLENGING!Oh and his accent is somewhat thick, for me it was kind of hard to distinguish between molarity and molality.
very easy class~~~take the evening class, the lab is shorter~~
awesome teacher!
Great Teacher. helps you out and has a great curve. He understands that there is a lot to learn. Chemistry is hard as it is and he gives you opportunities to bring up your grade
Great and helpful
Professor Li is a very humble, easy going person. He teaches you what you need to know for his exams. Just read the notes and ask questions when needed, he is always there to help. He provides practice test so you know what to focus on. I would take him again!
Mr. Li is a very good teacher, he teaches very clearly and its easy to follow his lessons. The class is kind of difficult but that is because chemistry is difficult. I have never learned more from a chem teacher, recommend to anyone trying to actually learn chemistry.
He goes easier on his students after each semester. He's good at explaining things, nice though terse about answering questions. His grammar's not great, but then again, he teaches chemistry and most students have worse grammar. He speaks Mandarin, too, just in case you were wondering.
Ok I guess. Sometimes he tests you on obscure things...but its not that hard to get a B. His tests are out of 20 so if you get 3 wrong you get a B...I got an A in his class because I got an A on the final...it was kind of a toss up. But in general easy to pass because labs make up a big part of your grade. Not the best at teaching
i had Professor Li for both chem 210 and 220. i ended up with a B in both but learned nothing. i just relied on the curve to get me by. his tests were very difficult and his lectures were, as well, very difficult to follow. I recommend taking this class ONLY if you're prepared to do independent study. I have nothing against Li, he's a nice guy.
He goes on tangents all the time. He keeps bragging about his wife who is a dentist and his child whom he referrs to as the little one. He tells you his 10 year old daughter is smarter than you. He is biased toward chinease students. Instead of using the text book he uses hand written notes on the projector. You can get an A but don't rely on him.
He is great with enthusiam. You will learn a lot in this class. one of the best chemist in school
Pretty good teacher. Nice, engaging, and helpful. Material is a bit boring. Didn't learn anything cool or useful. Exam questions are a step up in difficulty compared to the book/lecture, so try to find practice problems online or something to help study. Lab write-ups is a lot of busy work. Try to find good partners and make friends early.
Very nice guy as long as you show effort and show up to class
took him fro chem 210. fell asleep in most of his classes. his lectures are boring. his tests r hard. ended up with a B. didn't learn anything. nice guy. bad teacher. if you're taking chem to pass and not learn, he's the guy.
great teacher and very helpful
Li's a cool, funny guy, but can't teach. His test q's are pulled from somewhere else, not the book and are much harder and trickier than the ones he exemplifies in lecture. I didn't read the book, but you can d/l for free. You're job is to self study and to find you're own problems online to work on and you may ace it.
Good guy but can't really teach. He makes the problem harder than it actually is. And his test are ridiculously hard and its not from the text book. If he can't pronounce your name then he wont say it and all always avoid it (doesn't make an effort). Take his class if you are willing to work hard to get an A.
He doesn't really know how to teach, he assumes that you know all the information and doesn't really go over how to do certain problems. He makes his tests extremely harder then the book questions and what he gives during class. I would avoid him unless this is your only class, because its going to be difficult balancing his class with others
He is always helpful. A wonderful teacher to have.
Mr. Li is a nice person; he is funny from time to time and is probably affable outside of class. However, as a teacher he leaves a lot to be desired. He does not enjoy student questions, and makes you feel really stupid for asking them. His tests are MUCH harder than any examples he gives in class.
I had the worst experience in 210 this summer after getting a high A in 192. Li has the worst attitude towards his students which I found really discouraging. He doesn't seem to have any interest in his students doing well and brags about how many students fail his tests. I got a B in the class but got C's on most of his tests. Didn't learn much.
he is always helpful. He covers all aspects of general chemistry. I will highly recommend him
always care about students very helpful.
Love love love him so much , he is awsom
this class was more difficult then it needed to be. I had to spend hours restudying what he taught because it was so unclear. He paid barely attention to his students and was constantly on his phone during his lectures. I wouldn't recommend taking him.
Very helpful and organized
Very negative towards his students. Seems like he has no faith in his class, constantly telling us that most people fail his tests or get more than half of the questions wrong. His lectures are boring, with him yelling off the slides and 5 minutes of silence in between each slide. Be prepared to study on your own bc his lectures don't help.
He is caring and helping students to do well. He is warning students that his tests are hard. He is great.
Great teacher! Care for students. Responsible and knowledgable.
Knowledgabe and caring for students. Very Fair.
Lectures consist of powerpoints based off the textbook. He'll go over a FEW nonbook material questions to help further an understanding each lecture. The assignments, however, are on a completely upper level compared to what he teaches. Homeworks are insanely difficult if you have never taken Chem before & he assumes you have. He has an accent.
His quizzes and tests contain material that he doesn't go over enough. He doesn't give out study guides and the online homework won't help you enough for the tests and quizzes either. Unless you've taken Chem before or can learn by yourself, proceed with caution.
Knowledgeable and Caring for students...
Wonderful and responsible teacher.
Li curves the final curve sure; but gives hard tests and no homework. His lectures lack structure and cohesiveness. Simply put do not take him. Take Deline. If you just want to pass the class because of the curve go ahead, but if the class is crucial to your major or transfer do not take.
Lecture are he shuffling paper, akward silence in between (3-4 min). Poor examples, too fast to understand. Constantly in his phones. Blurry presentation because he squeeze 4 slide in paper. Test sometimes curved, but extremely hard. Challenge not accepted.
During our semester, he lost count of which labs were turned in, which affected our grade. Free-Response Final was take-home, but has a lot of typos and is somewhat hard. No extra credit, no matter how much you beg. A slice pizza does not make up for poor teaching.
He will cover the material thoroughly. He always cares about the students. He is always available to answer questions.
The usual grader; accessible outside of class to answer questions. Knowledgable
Great teacher and is very understanding.
He's very clear about what he wants and will most likely lower the curve at the end of the semester. Quizzes aren't too hard if you study, but tests are very hard. He's fair about grading and will review everything before and after the test. He includes stories in his lecture and is kinda funny. Cares about his students doing well, but have to try
First of all jimmy li is super intelligent. He can explain every single concept in depth and has a good way of explaining one on one. He is super caring and kind and likes to make jokes during lectures. His tests are hard but thats expected of chem 220. I would say the only downside is that hes a part time prof so hes not always on campus.
What makes a professor great is the process of teaching all the students by talking materials and asking them to do problems and checking with them to see if students did learn the material or not. This means multiple tests, feedback given from that test in detail, practice quiz, group quiz, homework. Jimmy is very respectful, but I expect more.
jimmy is very clear about what you need to excel in the course and makes lectures bearable by throwing in jokes. he is very approachable and offers extra credit.
Very nice professor, but the class is way harder than it needed to be. No homework which meant grades were broken up between lab work, three tests and the final. The first two tests the average score was a failing grade. Reads from blurry slides in lecture with very few examples. Lots of people ended up dropping the class.
The test tends to be hard. However, the professor does curve the test... As long you try, you will pass the class. He is very knowledgeable and respectful... You will enjoy the class.
Don't take Professor Li if you can. Most of his lecture just consists of looking at a ppt which you can do individually. He even leaves the class to text on his phone while we're doing problems. He gave a study guide once saying it was important, but none of the questions appeared on the test. In-class material doesn't prep enough for the tests.
Awesome teacher. Though he may be tough, he really wants you to learn. It'll be easy to pass, but it'll be hard to get an A unless you put in enough effort. If you aren't willing to study and learn, this class isn't for you.
Good professor. He's always willing to help. I took his class over the summer, and dropped because the course was really fast paced. Came back in the fall and it was a lot better. Study hard for midterms, and attend all labs to do well.
Only take this class if you've taken chem before. You REALLY have to know your stuff. His teaching style is throwing up a powerpoint, and that's it. Sure, he gives study guides, but they don't cover anything on tests (or just covers 1-2 basic questions). These tests are pretty hard and even his powerpoints aren't enough to study.
I took his chemistry 210 over the summer and of course it was pretty challenging but he does help you if you ask him. He is a very tough grader and his test are hard af but if you study a lot, do the study guides and ask him question, you can pass. His lab was very confusing sometimes but he would give us the answers if we were struggling.
I took him for Chem 410 in Fall 2018. He is more lenient to his students in this class compared to his Chem 210. There were times when I ask him questions, and he seems very irritated that I would want to know more about the topic. Very peculiar behavior. Overall, he's a good teacher, it just seems like he doesn't want to be there to teach.
Not a good professor. He reads off of ppt slides, and did not provide relevant practice for the students. I don't know if he has improved as a teacher, but when I took his class it was a nightmare. Zero guidance. Sure he curves, but that's not an excuse to be a sucky teacher.
Always asks "Are we okay?" to the class. No one ever asks me if I'm okay... so very heart-warming professor!
Prof Li is decent. The class is hard but it's chem so yeah... He could explain things more the first time but he will always stop and give examples if you ask. Tests are hard but the curve helps a lot. If taken in the summer you don't have homework so your entire grade is lab + exams. He's completely reasonable but you have to work for your grade.
Don't take summer unless you know material, no HW/practice/padding at all. It was TOUGH to get an A. Nearly half of students failing miserably by midterm & dropped - he seemed to get off on it, too. Smart guy but teaching sucked. Tests HARD, very weak lectures, labs hard to understand/manuals terrible, spent lots of time on his cell.
3 midterms and a final. Test are harder than problems on lecture slides - but the slides give you everything you need. Doesn't care about the lab, which can be a bad thing if you're confused about what to do. Just be sure to turn in all the worksheets. Textbook hw for 210, online hw (sapling) for 220. Helpful if you don't understand. Practice more.
60% and above is a C, 360 tests, 200 lab, 180 final, and 60 points for homework. If you make progress in the next test he gives out extra points.
Summer Chem 210 class with an online format. Lectures consisted of powerpoint slides from the textbook publisher and was basically read off the slides. Three midterms and a final along with lab reports, lab simulations, and homework. Recommended to have some chemistry background or else you might fall behind the class due to the rigorous pace.
Great, open for suggestion. One of the best professors in school.
Professor Li is a very understanding person, he always makes sure we understand the material and is always willing to work with you. Labs are pretty fun even though they're through zoom, lab groups turn into great study partners too! for sure recommend taking him
Prof Li was a clear professor. The examples on the slides were sufficient to learn the material. I took this class in the summer of 2021 completely virtual. Labs were pretty easy for the most part. Leave hours per Cengage assignment. Midterms and final exam were easy online, but study hard by doing every example in the slides & hw. Take Li!
Doing the labs are important and easy points to boost your grade. Doesn't grade harshly on labs and is very willing to help. Hard to get an A compared to most classes because the exams have harder problems than lecture and homework problems. C grade > 65%. Lectures are prerecorded. Class is in person.
lots of small assignments that boost your grade. 3-4 midterms and final are where your grades are mostly decided. LI is a nice and funny guy, but not the best at explaining everything in detail. notes mostly on powerpoints, but outside help is needed.
He's a good chemistry teacher.
Mr. Li cares for students. He is available during the class, after the class through Email or Zoom meetings.
Too many tests. Very difficult to get an A. Explanations don't make sense. Is not confident about what he's teaching. Grades are curved. Even if test is impossible you can still pass. Just do better than others.
Tests,ltures are heavy. took this during summer so it's fast paced. Must be dedicated to get A. Highly recommend having prior knowledge of chemistry or u'll def struggle. Makesure to ask him questions&he'll help u. all exams were multiple choice,but he did that to make grading easier for him. lectures are clear,but if ur confused,talk to him!PRACTI
I took Chem 210 online over the summer. I failed every exam but did all the labs and all the hw (which was like 600 questions or something) and got a C+. The test were pretty hard. HW is on Cengage and is assigned at the beginning of the course. Start early! It's a lot to do but it was helpful. For an 8 week summer online chem class it was doable!
Professor Li teaches a hard class but does a good job of conveying the essentials. He has several Cengage assignments and Midterms are easy if you can do the Cengages. I spent a long time studying the subject material, and I would recommend buying the textbook (Silberberg Principles of General Chemistry) off of amazon (used is like $4).
Tests are a lot, and they're weighted incredibly high. There are labs every week and a poster presentation, both of which are incredibly easy. The tests are really hard, though. The content of the course is really easy, but the test problems are hard. Make sure you read the book and remember how to apply the formulae.
He is pure evil, masked as a timid man.
Professor Li is funny, helpful, and always available. The summer class was fast-paced, but he explained concepts clearly. The course is tough, with lots of Cengage work, if you complete and understand those assignments midterms are manageable if you study. Prior chemistry knowledge is highly recommended. Be prepared to work hard,
You will learn nothing from this course, his lectures aren't coherent even for ABCs. He goes from ambiguous to lying on his promised for the midterms, labs. Everyone knows you take him to fit your schedule or because the others aren't available but its not worth it! I also caught him writing reviews for himself at class.
Very accelerated. Finished lecturing two weeks before we finished an 8 week course. Flys through lectures, sits on his phone, gets upset when questions are asked.
He spends most of the time checking on chinese emails instead of looking at experiments and asking questions. When he does look at experiments he is so angry he spent time from checking his chinese emails that he screams at the labmates. For anyone of chinese heritage I must warn against him, since he seems to call them out more often. Can't teach
I created an account here because he is an good professor, he just has the most unique style of teaching that is very hands off. He reminds you not to do it passionately. So passionately that your eardrums ring from his screaming, then acts very gentle in front of the chemistry dean. Like an good professorshould. He will tell you he is ireeplacable
He is the best professor ever, he will enhance your life, just ask him yourself. I JIMMY LI who lives at an tiny apartment at Saratoga to send my daughter to Saratoga high for an fate greater than my existence at Yonghe did not write this review. I am a chemiStry genius who will mention my wifes dentistry more than an advertiser gets paid for.
He does not like questions and even if your car breaks down or you have work or the dean and chancellor of the college believes you should have some extension, he will never give it, he'll be too busy playing chess online. He'll cancel his office hours and not let you ask questions most of the time. He doesn't know how to help.
He's a tough professor who often responds rudely to simple questions. His exams are 70% of your grade with no extra credit, and many test topics aren't covered in his lectures, though some questions are easy). I also dont recommend his teaching style and the way he calls on students.
The class was challenging because the grading relied heavily on small assignments. The class average was about 53%. Homework was only 2 points each and classwork about 15, so every missed task had a big impact. Staying on top of everything was essential.
