"Tough Grader"
As a student it's your duty to get help when needed. Professor Ly is a great professor IF you utilize him correctly. He's tough, but it only means he wants the best from his students. He gives you the tools and he expects you to hone your skills with them. Math is not an overnight thing. Pay attention in class and you should be fine.

Mr.Ly wants students who work extra hard. He is a hardworking man himself, he is a good guy if you get to know him. He gives a lot of hw especially in the summer. I believe if you can handle his class, you can handle the higher level classes. He knows who are the hardworking students in his class.*most of his questions on the exams are from the hw*

This teacher can lecture that good and has a strong accent. However, he grades really easy and 90 percent of the credit just for setting up the problem the right way. If You know your stuff take him and guarantee A for Cal 1,2,3 and DE

Prof Ly is a really good teacher. He doesn't teach exactly from the book but, if you didn't understand what he taught then you can always refer back to the book. Be prepared to do tons of hw. And to learn math, practice is what makes perfect. You can't learn math overnight so it's good that he assigns a lot of homework.

TI89 allowed on all tests/quizzes. Quizzes are 20% of grade, tests are 45%, and final exam is 35%. You can get up to 110% on tests if you do the extra credit. Quizzes/tests straightforward. He will tell you everything that will be on them beforehand. If you're "good" at math, this is an easy A.

Math 420 Taken for Credit:N/A Attendance: N/A Textbook Use: What textbook? Rater Interest: Low Grade Received: N/A 
Just plain horrible. Doesn't finish his sentences when speaking. He repeatedly needs to clear his throat every 3 words in a sentence and next to impossible to understand. When writing on the board, he jumps around on multiple parts of the board, making it difficult to follow along. He writes middle, then left, then right on the board.

Math 420 Taken for Credit:N/A Attendance: N/A Textbook Use: Barely cracked it open Rater Interest: It's my life Grade Received: N/A 
Had to take the community college route because freshman priority doesn't cut slack at Sac State. HARDEST MATH CLASS OF MY LIFE (even doing really well in Calc 13). Literally impossible and 3 page long problems (often picks the hard long ones). Hw not required. In this class, a dumb mistake at the beginning of a problem goes a long way...

VERY BAD ACCENT. SOOOOO MUCH HOMEWORK..literally 58 hours a week. He's nice I'll give him that. Not helpful at all however, does not explain things clearly. I took him for Math 120 ended up dropping it cuz I was failing then I retook the assessment test and got into Math 300

Don't Take This Teacher! I should have seen many red flags! 1 He writes his own book 2 Answers are wrong so you will waste time trying to get the answer he gives 3 His test questions use only 2 or 3 of the easy topics from the chapters and the rest are the very difficult ones. 4 I was in math lab every week to try and understand what he taught.

Really hard to understand. I had passed trig and pre cal before but couldn't do his class. He is way to hard of a grader, I got failing scores for right answers and good work because I didn't answer the problems his way.

He has a very heavy accent. Plus, he did not use a textbook, so I transferred into another section with a different professor.

Professor Ly does not teach this class with a textbook, he passes out lecture notes, which is essentially all you need for this class. The homework has good examples. I don't understand why precalculus is required, precalculus is basically a review of this class. If you take this class, and get an A, you'll definitely be prepared for Calculus

Professor is great. Spend 58 hrs a week studying/doing HW and you'll pass w/ an A or B. If you completely suck at math like me, then 813 hours a week study. Lots of HW but it prepares for quiz/tests. Tests are made of moderate HW problems. From observations, ppl juggling between job and school may have a difficulty w/ this class. Learned a lot!

Absolutely HORRIBLE! he never answered questions on the homework all the way through. He assigned too much homework and graded every hw assignment in a stringent manner, deducted points for everything! His accent made it hard to comprehend what he was saying sometimes along with bad grammar and spelling on tests. AVOID HIM!

Ly does have an accent, and sometimes it may be unclear to understand what he is saying. He makes his quizzes very comprehensive, including the concepts he explains during lectures. DE is a very complex course, and Ly did a pretty well job, although he did make several mistakes, teaching the subject. I would recommend Ly for Differential Equations.
