Drop this guy like 3rd period french!!!

Shall i saY hes very hard to understand.. If u haven't had any sorta of trig or what not... u will be lost...

When we ask how to work he responds "It's just a feeling".

you will fail... the language barrier is just too big. He can't explain things to anyone and he puts new material on the exams. I did all my homework and the reviews and still failed... doesnt seem right does it?

The man is obviously very smart and knows his math. Unfortunately his english is so poor he cannot undestand and answer basic yes or no questions. Sadly, I'm not exaggerating. Please don't even bother. If you need this to graduate, graduate late.

WITHDRAW NOW, DONT EVEN BOTHER. The material taught is not too hard but with him teaching, theres no hope. Half the class is failing. Seriously, drop it and take another teacher. He's asian and you can't understand a word. Ex.He says "broom" for

If you dont have a solid background in Calc from highschool, YOU WILL FAIL! He skips so many steps in examples that its impossible to understand, uses exact examples as book yet does not elaborate.He also cannot understand students when they ask questions

He is a "professor". He knows Calculus. He is there to teach. Whether he is good professor or not, that is up to students. But I tell you this. He never smile. You can see what kind of person he is by looking at his face.

good luck...

C'mon guys? Nobody cares if you had Cal in HS, this is about YONG! His LEAST Concern during this course will be YOU as an INDIVIDUAL! I waited over an hr. o/s of his office while he helped someone w/ their economics (his office hrs are for math); Fine. When he was finished he basically brushed me off, W/30min left For his Office HOURS! STAY AWAY!

Had him for Calculus the Fall of 05. A genius, mathematically. Never in his office. Never answers e-mail.

Dr. Yong has no people skills and only teaches straight out of the book. DO NOT TAKE HIS CLASS IF YOU WANT TO PASS!

To put it simply, this professor does not teach. He reads the examples from the book, one by one, and writes them on the board. He also believes you should have every bit of mathematical knowledge from previous classes memorized. He is unreachable by office, e-mail, and phone. AVOID.

At least you guys actually had examples. He refused to do them for our class because he said "this is an upper level math course and you should be teaching yourselves." Not a happy experience at all. Don't know how he is with other courses but I would say avoid him for this one.

worst teacher ive had in my whole UCF career, i regret it so bad... first of all he didnt have a book for the class, he didnt show examples at all, it was str8 up theory n proofs on tensors which is an extremelly abstract concept he never solved any problems in class, his take home tests were impossible to solve, AVOID AT ALL COST he is TERRIBLE!!!

I cant believe they let this guy teach. It was an awfuul experience so get out of his class if you have the chance.

Dr. Martin is more the teacher in one day than this guy was all semester. Yong is Horrible!!! I did well in his class because I taught myself! He made me feel like a worthless waste of time when I went to his office. Don't take!

This professor does not care about his students. Everything he says and does in class comes directly from the book. Do not take him unless you have a strong background in Calculus. Horrible teacher.

DON'T TAKE HIM! I'm in his class right now and I wish I could get out. Yes he's a genius, no argument there, but he is horrible at conveying that knowledge to you. I ended up teaching myself. He doesn't curve the tests. So far only two people have made a's out of a 40 person class and 4 tests. No curves, no extra credit, no mercy.

This has gotta be top three worst professors I've ever had. He comes to class with pages copied from the book and just copies it to the board without explaining in real words what anything means. His proofs are a joke. He doesn't take anyone's opinion into consideration and when your supposed to take a final on one day, he makes it 5 days earlier.

Professor is very unclear. He words things differently on tests then how they're presented in book, and I believe this is where everyone trips up at. Because he teaches verbatim from the textbook, we expected some consistency. Grades progressively got worse. A third of the class failed test 3. There's no curve, which is absurd.

Class is not impossible, but professor is. Makes the material way harder than it needs to be, and doesn't understand that the material is difficult. Can have a condescending attitude when you ask questions he feels are "trivial," doesn't explains concepts in an easily-graspable way. He does definitely know the material.

You have to teach yourself ALL of the material. 94% of the class failed the first test. RIP GPA.

Awful! He is a reputable in his field and has delivered a keynote address at an international conference. He could care less about his students and the department is scared to reprimand him at all. Says the quiztests will be on one thing and gives another. Likes to brag that he wrote questions none of the graduate students can pass on the quals.

if you were like me thinking calc2 was the most difficult well calc 3 is no cake walk. He's smart like SMART, relaying his knowledge to students not so much. He teaches from the textbook. If you read the text book it's basically identical to what he says in class 3tests final is 55% of grade. Tbh don't know how I passed maybe cuz so many dropped it

This guy is very smart. However he is possibly the worst teacher at ucf. I am a 3.75 student and put 40 hours of studying into each of my first two test for this class. Still ended up having to withdrawal. Going to his office hours proved to me he doesn't care about students. DON'T TAKE HIM, HE DOES NOT KNOW HOW TO TEACH OR EXPLAIN ANYTHING

Not a great professor to take if you are not already confident in your calculus abilities. Exams are difficult and he will often choose very specific problems to test you on that he might have only gone over in class once. He was not very helpful in office hours, he expects you to learn on your own. Known to laugh at student's questions in class.

THE hardest math class that I have ever taken. Grade is solely based on 3 tests, Final, and weekly quizzes. What makes it worse is that he chooses specifically hard and confusing questions over material that he covers poorly. WARNING: He will try to trick you if you don't know what you are doing. Take another instructor and avoid perpetual failure.

The worst professor Ive had in my entire life by far. Incredibly difficult to understand what he is saying, unclear explanations, and puts trick questions in very short test. Super bad professor.

AVOID AVOID AVOID, please don't take him, for any reason, I had no choice but taken him but I regretted it, every week has a quiz, HARD GRADER, he doesn't even read your answer if it's not the same his way, most of us failed the class, we were only 14 students. No extra credits. it was the worst decision ever that I've taken

Due to the limited words available, this shall be rather brief. The $80 textbook is simply his lecture notes printed up. He doesn't like questions on his convoluted definitions of simple ideas. He forgot to upload the midterm and only gave us 12 minutes to do the 90 minute exam. He changed the online final to in person right before finals week.

DON'T TAKE HIM UNDER ANY CIRCUMSTANCES !!!

Don't take him. That's it. Take literally any other prof. He doesn't care if the whole class failed, he will not curve. He is brutal and ruthless and gives almost 0 partial credit on test questions. No cheat sheets, and doesn't care about students at all. Do not get this prof due to the class times, its not worth it. Take the later or earlier class

Do not take this professor. He will read off of premade slides and not explain any of the concepts. If asked to do the practice examples on the whiteboard he will not explain at all what he is doing and leave an unreadable solution. Tests are extremely hard and use extremely niche integrals.

If you take this class with Dr. Yong you will be teaching yourself the majority of calc 3, this is the first class that truly gave me a run for my money and I believe that with a better professor i couldve understood the class more. He just reads off of powerpoints and does no problems with the class and the exams have very niche problems.

Differential Equations is a fascinating subject. Take anyone else In favor: Replaces lowest test with final Homework is good bump (20%!) Against: Not the best teacher, reads off PowerPoint the whole time Doesn't work through examples in class, only shows the answer (often the wrong answer) Attendance is 3% ex cred so I did homework during lecture

Truthfully the worst professor I have ever encountered. Did not answer a single question asked of him, or really explain anything. Words cannot express how terrible this professor is if you struggle with calc at all. I hate it here.

I would rather chew off my own arm than take this class again. This is the worst professor at UCF and I had to talk to the department head about this. His grades rely almost entirely on tests. He does not care if you fail. He refuses to actually teach, doesn't answer questions, and he ends class an HOUR early for no reason. Avoid AT ALL COSTS!

I couldn't understand him, and he laughed when we asked questions. He seems like a nice guy but he grades very hard and the tests are even harder. I would never take him again but I've learned to go on rate my prof before picking a class now.
