I thought this guy was good in the beginning, then I got his first test and it was like a ton of bricks hit me in the face, He told me i would be fine and then i ended up with a 55%. AVOID AT ALL COSTS
Dr. Loi is by far the best math professor that I have had at Wright State University. He is clear in communicating math principles and his exams and quizzes are mildly challenging (if you have done the homework and actually studied). Highly Recommend.
No Comments
Dr. Loi is as great professor. It is hard to find professors that can actually teach and are also fair. His tests can be rough but if you show improvement on the final he gives you the benefit of the doubt. I would suggest taking Dr. Loi!!
Professor Loi is a great teacher. He is extremely helpful and will always help you out with any problem you have. He is very fair and does an excellent job of teaching math. He is awesome. I highly recommend him.
Best math prof at WSU. Very helpful if you have questions. Expects you to do the work, but unlike just about all other math teachers here, will help you if you struggle. Definetly recommend!!!!!
Very unclear, crappy grading policy
THIS GUY WILL KEEP YOU IN A CLASS DURING A FIRE DRILL!!!! IF YOU WANT TO BE FINED FOR NOT LEAVING DURING A FIRE DRILL...I SUGGEST YOU LEAVE WHEN IT STARTS, NO IF'S, AND'S, OR BUT'S. Some words he say is very funny, other than that, and good professor.
The Phan Man is great. He's a really good prof, and not too hard to understand. His class is pretty tough though, and quite a few drop. However, if you go to class and lab, and ask him for help, you'll do fine. Phan Club for Life!!!
His tests are REALLY hard!! I studied for 2 weeks and failed it with flying colors and I was screwed for the rest of the quarter! FYI if you get him get out of the class!!!
Dr. Loi is the best prof I have had at WSU. He is always willing to help. His exams are tough but fair.
I highly recomend this teacher. one of only two teachers at WSU in the math department that can actually teach.
Makes numerous mistakes in his endless examples during lecture, but has absolutely no mercy on the quizzes and tests. The test questions were structured nothing like our homework or quizzes, so I felt kind of cheated by the end of the course.
His lectures are boring but the man is wonderful. He actually wants you to learn. He is by far one of the best math professors at WSU. Take this man! I got a H and I'm horrible at calculus.
He is a really friendly man. He is one of the few profesers that seem to care. However, his exams are verry difficult. The questions are nothing like we had practiced in class. I felt class time wasn't well spent.
Easy professor and he wants you to learn. I'm dumb in calculus and I got a B. He wants you to learn. He answers questions without making you feel stupid. His grading policy is screwy but what can you do?
Even though I got a "below average" grade in his class, he is a good instructor. Very easy to follow his notes and he is very helpful. Just watch out for that final, though! The stuff on there looked NOTHING like the stuff he went over in class. Overall, he's good!
I studied for 2 days straight for a test, and failed horribly. Don't take him, his tests are so random.
I heart Loi! He's the best mth pro there. His notes are very organizedanddetailed. He explains everything until everyone understands.
Prof Loi is the best prof ever! His teaching is so easy to comprehend and he makes learning calculus easy. Take his classes whenever possible.
Great Professor! Explains examples really well in class. Gives quizes almost every week but they end up helping your grade. Tests are somewhat difficult but if you just pay attention in class it is easy.
Not a fan of this prof, very boring. Inconsiderate of students...acts like he's teaching high school.
He is a great guy to take if you want to understand the basic for calculus I
He is such a nice teacher, if you have any troubles with anything just go to his office and ask him. He would his best to make you understand. You should study for his tests and quizes
Took this class with another teacher and failed retoke it with him and have gotten nothing below a B. Cant wait to take him for Calc!
Horrible, hte problems on his tests and quizzes are a lot different than the problems he does in class. If you take him you will fail. GAURANTEED
I only had Dr. Loi for Calc 3, but I thought he was a really good teacher. He explained things thoroughly, and he was always willing to help out any student without belittling him/her. His tests are not easy, but if you take good notes, do the HW, study, and ask him about things you don't understand, you should be fine.
Dr. Loi has really high expectations for his students. He genuinely cares about how you do in class and does his best to answer questions. There's no doubt that advanced linear is tough and Dr. Loi tried to be as clear as possible. Make sure you do well on homework and know your theorems too. Dr. Loi is one of the better profs in the math dept.
His tests and quizzes are hard but he explains things really well in class. His notes are easy to follow and he's such an intelligent man. You have to study the problems in every section of the book because he takes those problems and changes a few things around.
Kind of ambiguos tests, but easy if you know the material. Wants his students to do well. Don't disappoint him...
Dr. Loi tries to explain the material in words, when it would be easier with pictures. So you are going to have to make sense of the material for yourself. Once you can convert his class notes to a drawing (it is Trig), you will get an A. The quizes (which are never pop)are harder than the exams, so be ready for them. He loves students who try!
Dr. Loi is a good professor, unfortunately I didn't study as much as I should have, but I don't fault him for that. I always was able to understand him in lecture and was available and encouraged to help after class. As long as you study the material and his examples you should probly get a decent grade.
Decent prof. Sometimes make mistakes in notes so don't be afraid to ask if you don't you don't understand what he said. writes a lot more than what needs to be during notes, but almost always pushes midterms back at least a day.
Studied 12+hours for a midterm, failed it horribly. Makes it hard to make up for bad exams, with homework/labs only being 10% of your grade. questions on exams/weekly quizzes not represented in notes or homework given.
He's a cool guy. He kinda reminds me of my dad
The nicest guy! He really wants everyone to do well. Loves to see people come in for extra help in his office hours. However, he does use mathamatica in lab.
Not a terrible prof, but definitely not great. It seems he made Calc1 harder than it actually is. Teaches in proofs, which I can't learn with. Midterms are challenging, even if you study; however, A's are entirely possible. Lab is worthless, as with any calc-lab at WSU. The final is ridiculous, but he gives extra time (45min!).Take Zhou, if you can
Ok Prof, nice guy, but very difficult. Homework and quizzes every week, Which are fair, but very challenging. Tough grader, and Tests were hard. The Final was absolutely brutal, but he does give you alot of extra time. If your confident in your math ability, go for it. Hes a fair teacher, just challenging.
CLass examples dont correspond to homework. Homework doesnt correspond to exams. Very condescending when questions are asked. Hard to understand and bad hand writing, worst professor i've ever had.
Tests don't really match anything he covers in class or on the homework. His grading is awful, you'll miss plenty of points for questionably small algebraic errors. Ruined my 4.0 beforehand, with plenty of harder courses, I got a D. Stay away if you can.
Good professor. Gives great examples. He wants to help you. If you do the home work, his test and quizes are easy.
Takes a lot of notes which correspond well to the homework.First exam was cake but the material gets much harder after. Second exam was very difficult and the final was next to impossible. Best advice is always go to class and do all the review problems before the tests. Not impossible to get an A but incredible difficult.
Dr. Loi is one of the best math profs I've had. He has lots of energy going into the class, but he does get annoyed when people ask redundant questions (i.e. he just said the answer to what you just asked). He gives weekly quizzes, which directly relate to the test material. He is very generous on the partial credit for tests, too!
Gave good notes in class but they don't always relate to the homework and tests. Midterms were very hard. For my class he had to give out extra credit and reteach a chapter because everyone failed the second midterm.
AVOID! Test and quiz examples are much harder than those given in class. I went into his office for help nearly everyday and he laughed at me when I told him I didn't understand. Does not care about helping students one bit. Got tutoring as did 5 others in my class of about 20 students, and still could not pass his quizzes or tests. DO NOT TAKE HIM
Very difficult class made more difficult by the professor. His quizzes and tests are extremely difficult, and he suggested everyone in class get help by the third week. Questions on final were not at all what we went over in class. No curving of tests, even though the majority of the class failed.
Horrible professor. Quizzes and tests did not reflect any of the example problems done in class. Unfortunately, he knew the entire class did not understand the material and still moved ahead with new material instead of trying to help us understand. Everyone continued to fall further and further behind, and our grades reflected so.
This is probably the worst professor you could have in the Math Department. Can't understand him when he talks,and he doesn't want to help you. He always says "this is what I think your trying to ask" and no, it was not what I was asking. Take the class with Ray Otto. Any of Ray's classes are exceptionally great.
He goes over all the easy problems in class and puts the most difficult ones on the exams. Taught myself everything I knew. Had a B in the class before the final. Came out of there with a D. 30% of the final I had never seen before. He told us he didnt have time to help anyone outside of class and that we should all get tutors. WORST Prof ever!!!!!
His tests are very difficult but certainly not impossible. If you are struggling, get help early (recommend tutors and/or math learning center.) His lectures are very clear if you have read the book or worked through some problems beforehand. Be careful if you have never taken calc before, he has a reputation for difficult tests.
Very hard exam maker and the final was very hard we had a question that we didn't talked about it. His review for the final is totally different than what we had in the final exam questions. He is very nice guy but not an easy calc prof
Very hard professor and his exam are very hard too. His review for the final is totally different than what we had in the final exam questions.Never take any class with him again. dont take any class with him.
He is horrible prof! Doesn't care how much you understood the object, doesn't wants you to go to his office hour majority of the class failed
Very hard class to take, and his review before each test has almost nothing to do with his test.
I want to rate him higher but he does teach a tough subject and it is hard to understand some of what he says. As far as Calc is concerned I got a fair grade and he was helpful when I didnt understand.
Loi is one of worst teachers I have had in my life. He uses his stupid projector to explain his stuff but the problem is, his hand's writing is more like chicken scratches. So you will not understand anything. And if you ask him he gets mad unless you are a girl. His tests are extremely hard + hard grader+ no curves. AVOID HIM.
Hes old school, uses over head projector still and has horrible writing. He also comes up with the most rediculas test questions that are next to impossible to answer. He's also one of the toughest graders I've ever had. Stay away
Great prof. He teaches gives lots of examples and tells us what will be on test and quizzes. Homework is mandatory but it is very helpful. If you don't pay attention or put forward effort, that's your problem. Tests and quizzes are fair. If you know the material, you'll get an A or B. If you don't, you'll get a bad grade.
He goes through the example problems really fast and gets confusing throughout it. Ask question to see if it gets better but some times it makes no sense.
If you go to class, do the homework without cheating, and study, you will manage an A or B. His weekly quizzes and exams are no more difficult than the homework problems - so if you half ass the homework then you won't do well. If school is canceled, he will push assignments back instead of piling everything on you, unlike a lot of professors.
Took him for summer term so he had to teach a little faster but he would slow down and expand on topics if you asked. If no one asks questions he just assumes you get it so ASK!! Overall he's a great teacher and a fair grader. Study the quizzes and homework for the exams and you'll be set; the questions aren't "harder", really, just longer.
He is more than happy to help you in class, after class, and in his office hours. One student today actually was stuck on a homework problem and we went over the entire problem in class. He gets excited during lectures and keeps it interesting. Can't have a conversation without this guy smiling. He is a moderarely tough grader and tests are weekly.
Dr. Loi seems to be a pretty nice guy, if you go to his office he is willing to help. But it seems to be he does not seem to explain the best of things. Moreover he seems to do the easier examples in class, but on the exams, it throws you of the curve.
Phan did a pretty good job throughout the semester. His lectures are helpful for the homework and will you set you up nicely for the exams. The quizzes he gives weekly definitely help you continue to stay up with the material. If you do the homework and put in a little time outside of class, a B is very manageable. Be aware, he grades very tough.
Professor Loi tried to teach Calc II casually, and I liked his teaching style. Don't miss lecture, though. In grading, he tends to focus more on the method than he does on the result, so pay attention to detail.
Avoid this instructor
Don't take this professor. He takes off too many points for small errors and doesn't take into account the methods used. He is a very harsh grader and does not curve at all. His curve was a extra 20% on the final in the form of more problems, aka not really a curve. You're better off finding another professor outside of Wright State.
Expect homework weekly. Exams were very tough. Also he says he gives partial credit, he only gives it when you are doing the correct process but mess up a negative sign or number in the problem. Very hard grader. Exam averages for calc 3 were in 50-60%. Copies notes straight to board
No curves. Insanely hard grader. Find a different professor.
Horrible grader you won't pass unless you can fully do each step of every problem correctly the smallest mistake on a problem worth 15 points will leave you with 2 points for that question.
Loi is a really good professor - as far as teaching. His exams are insanely difficult, with little to no curve meaning you're gonna have to work many hours outside of class. If you're dumb (like me!) I would suggest another professor. Grade breakdown consists of 10% for hw, 10 for quizzes, 15 for 3 exams, and the final is worth a grade-reducing 35%
Notes straight to board. Very specific quizzes every week. When grading, nearly all or nothing.
Phan Loi is a great professor for calc 2. Although his grading is ridiculous. The first time I took his class I got a D. The second time i got an A. Although i had to retake the class for a second time I would still highly recommend Phan Loi just be prepared to study for every exam and review all problems done in notes they tend to show up on exams
Solid prof for MTH 2310. Difficult class, but he cares that you understand the material. He gives plenty of examples in class for each concept and there aren't many surprises on homework, quizzes, or exams. He's a strict grader, and you'll need to study a lot, but you could do a lot worse with other math profs.
Great lectures but make the examples so easy for notes and the questions on exams much harder. He does not use Pilot lot so you have to calculate your grade yourself. He does not give partial credit when grading. He knows what he is doing and expects the same from you.
Doesn't care if you can do the calculus (what you're there to learn), if you do everything right but screw up the algebra or put a negative when it should be a positive, you'll get only 1-2/10 points on that problem. Quizzes have 3-5 problems, exams 6-8, so if you screw one or two up then you fail. Likes to treat students who ask questions as dumb.
Dr. Phan Loi knows his field very well. That being said, every time I asked him a question he treated me as though I was an idiot. His examples are extremely basic, which make his quizzes and tests super difficult in comparison. His grading is absolutely awful, little to no partial credit. Any mistake leads to failure.
Is highly condescending when asking questions, does not attempt to personalize the class, lectures are simply writing and erasing stuff from a chalk board, does not use Pilot (electronic class tracker) like all other professors, gives little weight to homework and huge weight to exams, looks at ceiling when talking to you.
It is obvious that he knows the content, but he does not teach it well. Every class consists of writing things on the board and erasing, nothing more than that. When asking a question he treats you like you are an idiot. His in class example problems are incredibly easy, where the exams are very hard, also exams are 75% of the final grade.
Nice guy, decent at teaching, very harsh grader. Gives no curve. Other professors in the MTH department will gives 15% grade cutoffs, he does not.
Dr. Loi's class is the hardest class I have ever taken. Not because calculus 2 is hard, but how he teaches the class makes it harder then it needs to be. If you make one mistake on any question for quizzes or exams then it is more likely than not you will lose all the points for that question. I suggest avoiding taking this class under Dr. Loi.
Dr. Loi is a very knowledgeable professor. Calc II w/ him is not an easy class. He gives weekly quizzes & HW is due every week. He is a very tough grader & that can really get you in tests and quizzes. However, he is easily accessible outside of class and that can help a lot if you are struggling. Overall, hard but not impossible.
He doesn't properly prepare students for the material on the test, gives little to no partial credit, and never curves. The only people that do good have retaken the class 3 times. I am normally an A student and I got 2 Ds and one Cs on the exams even with studying for hours. Plug in one number incorrectly and you'll get 10 points taken off.
Phan Loi has very well organized lectures. That is the only upside. His tests/quizes are nearly impossible. The questions focus on specific cases where complex algerbra must be used. The final was the hardest test I've taken in my life. Only 3 of 15 I asked passed the class. He is a big part of why Wright State's math department is a nightmare.
Before I took this class I was on deans list with high honors routinely. I studied for 12-18 hrs for each exam, 6 hrs for each quiz, and still probably barely managed to pass the class. His lecture examples barely scrape the surface of the complexity of the exam problems. The only good part was my 96% average on the homework. Avoid if possible.
Lost my 4.0 GPA to this professor. Lecture examples are too simple, exam questions are too complex. Second half of the semester (online due to COVID-19) was made up of super-short video lectures and forced webcam use for tests/quizzes; also had to buy a printer/scanner on zero notice to do quizzes and exams. Avoid at all costs.
Lin Alg- Phan struggles with virtual teaching. This was the easiest math class I have taken at WSU until Covid. He has all his notes typed up. I would recommend him for in-person classes, but not online. He offers many virtual office hours, so those could help you. Only reason I got my final grade is because he curved it. Being nice goes a long way
I thought i had it bad taking trig with svobodny but phan loi seems to challenge the level of bad teaching. his online teaching consists of PowerPoint slides that have a problem worked out on them... found youtube vids of another WSU prof that teaches better but phan loi makes the inclass examples and homework easier than the quizzes and tests.
Absolutely awful curriculum. He went about teaching this course all wrong. His lectures did nothing for me. I along with a few friends had to self teach the course and it did not work out well. I am currently taking the class with professor Xhou and he is a much better professor. I recommend waiting until he is available instead of taking Phan Loi.
Professor Loi gives very unfocused lectures, and while it's obvious he knows what he's talking about, he does a poor job getting it across to the class. The worst part, however, are his quizzes and exams, which are much more difficult than anything examples he gives, as well as taking away 80% of the points for a minor algebra mistake. Awful class.
Loi will teach you everything you need but then expect equal dedication from you. He is a tough grader, (point off for missing +C) but that prepares you well for the final. If you do well he recognizes that. The Mathematica labs were pointless but contributed to grade positively. Gives clear feedback, notes are extensive, and provides solutions.
Exams look nothing like text book problems or in-class examples. It does not matter how much you study for exams, it will take a miracle to pass. You will think you know the material well and be completely lost on the exams. I would like to rate the exam difficulty level EXTREME. Do not waste your time and money.
In spring 2021 this class was fully online. Phan Loi used PowerPoint to explain basic concepts and then followed them up using extensive examples. The homework and exams were of the same difficulty level (I believe there were three midterms and a final). He used lockdown/webcam but provided feedback and had sessions after exams to discuss problems.
