He wrote his own book, which tells you that he knows his stuff. you miss a day of lecture? your doomed. Since he goes thru literally 2 sections a day, which means a lot of hw. If he didnt finish a section, he would run thru it in the last 5 minutes of class and expect you to finish the 20-35 questions on the hw. furthermore the hw takes about 2-3hr

Professor Ly is extremely helpful and very clear. He cares about his student's grades and he always gives extra credit on exams. He goes over every question students have on the homework which is extremely helpful. It all depends on the student. If you show up to class everyday and you try, you will probably pass.

Lap Ly teaches you various aproches on how to solve problems. He takes the time to grade your work which can be helpful. The major problem with his class is the immense difficulty. If you get a C on the homework you fail the exams. Independent study is required In addition to boring yet thorough lectures.

I really appreciated Professor Ly's class. He is a good teacher and makes you work for your grade by giving a lot of homework each night, but this actually really helped me understand algebra even better. In addition, he is very approachable, he drops 5 lowest Homeworks, 1 lowest quiz, and will accept homework put underneath his door after class.

His class is very easy. He goes through lectures really slow so its easy to keep up if you're a slow student but its painfully annoying if you aren't. He allows you to turn in late work to his office. Tests and quizzes are basically the same as homework. He tends to split chapters though which gets slightly irritating. All in all, its an easy A.
