His English is very difficult to understand [written/spoken]. When you ask a question, he answers everything but your question. Don't bother buying the textbook, you use an online software that has the same stuff on it. Basically, you're going to be teaching yourself. Good luck with that.

Professor Bin Lu is a truly nice guy and cares about his students and their success! The work is not too much and not too difficult. There is a lot of extra credit offered and his worksheets are very similar to the tests so study/do the worksheets and youre good! His handwriting is hard to read sometimes but overall it was an easy and good class!

If you don't attend classes, you most likely won't pass. the professor sometimes is hard to understand; but has a kind heart. He was supportive of his students, but some of the material was hard to grasp because the homework either needed to explain more clearly or the lectures needed clarification. Three exams and a final, quizzes, and hw online

Homework if done before the due date is extra credit. Allows 1 notecard for tests and 3 for the final. The class is hard and some of the stuff is hard to grasp. Dropped the support class-wasn't helpful to me. Only graded on tests and the few points for the homework. Doing the homework early helped me get a C. Ask for help!

I struggled in class purely because his handwriting and his accent is really hard to understand and to read. I cannot copy his notes and it made class basically self learn by yourself for the whole semester. Which was already hard to do since it's your first time seeing proofs. Don't take him his test outlines don't reflect whats on his exams.

the difficulty of the course was a 2/5 but the way the professor taught it made it much harder than it had to be. based lectures off of assuming you already knew what he was talking about. the lectures were fast and hard to understand. make sure to show up to class and take notes. he doesn't teach, just shows you what to do. 3 midterms and 1 final.

Easy class and professor. You can use index card and calculator for exams. His exams are problems from the worksheets, so study them and you are good.

Tells students to change majors if they don't get a concept. Stands close to & hovers over students. Celebrates when students drop class. Test outlines don't reflect what's on exams. Doesn't know the answers to & can't explain homework he assigns. Laughs during lecture, illegible writing, goes off topic. Doesn't mention where material comes from.

He goes over the material so fast that he does not even explain it to you properly and because he goes so fast he tends to let class out early. During the class, you will have 2 weekly quizzes and 2 weekly homework assignments. What makes his class harder is that he does not speak English fluently so it can become hard to understand him at times.

The teacher is okay and goes over everything quickly like if you know it off the top of your head. However, homework is online, and quizzes. So, it's easy to have a good grade in the class. The exams are in person but allowed to use one flashcard front and back. The only reason why I would take him again is that flashcards are helpful in exams

His class is free. If you do the homework before its due, you get extra credit on it, which is a huge grade boost. His exams are weighted quite heavily but if you do the handouts, you're more than okay. For god sake, attend this class and DO NOT SKIP. only reason i am giving him a 4 is because he is hard to understand at times.

DO NOT SKIP CLASS ESPECIALLY A MATH CLASS! The class is free otherwise. Make sure you do your homework before the due date to get extra credit point (you'll NEED those). At times he can be hard to understand hence a 4. Make sure to PARTICIPATE and FOLLOW ALONG! The exams will be your study guides just with different numbers! DO YOUR STUDY GUIDES!

The Homework and quizzes are online; therefore it is easy to get a good grade. However, the exams can be very hard. It is difficult too because he does have a heavy accent and it is hard to understand him at time.

Professor Lu cares a lot about his students and their success! He mainly does textbook problems the entire class and will give definitions / formulas. He gives out extra credit for doing the homework early and also has study guides for the three exams, which you can use a flashcard for. I would like his class a lot more if it wasn't at 8AM though!

honestly all you have to do is really put in your own time and learn the material but if you ask him any question he is pretty helpful and lenient. Definitely reach out to him.

Professor Lu is very caring about his student's success. His exams are difficult, but he allows notecards. Tests and Quizzes are online through Cengage. If you do the homework 24 hours before it's due, you'll get extra credit. DO YOUR STUDY GUIDES! His class is really easy only if it wasn't at 8am.
