You really need to attend class and practice to do well in this course. I went to all lectures(2013 Fall) and we were 2-10 attending his lectures by the end of the term.

Everyone should take JayJay as their first teacher at McGill University. His lectures will inspire you to discover the art of self-study and you will not fail a class ever again at McGill.

Xu is the absolute worst. He is not clear in his explanations and of no help whatsoever if you ask him a question. Exams are tough. The questions were doable but all unnecessarily long.

They say if you haven't taken a class with Prof. Xu, you haven't done Engineering at McGill. Indeed, the infamous Lord JJ will push you to the utmost limits of sanity, as you frantically attempt to understand ANYTHING in lectures, sacrifice many hours to keep up with his blazing pace, then have everything you ever knew crushed by his ruthless exams

JJ Xu as we call him is the worst math prof at McGill. No one can understand what the professor is saying. Midterm and written assignment due on eleciton day when administration emailed: "Professors and instructors are urged to avoid the scheduling of tests on October 19." Does he not think we have other classes?

Avoid or take his course just for fun! If you have to take a course with him, suck it up and don't ever defer your exam. I deferred mine and it was a big mistake. I read the whole textbook, understood it , did the regular exam,thought i was fine and I was wrong. The deferred exam is at least twice as hard as the regular one. lol

Comment:
It's almost funny how bad of a teacher he is. Spends the class talking to the board. Attendance rate was about 12 students on a good day. His handwriting is borderline undecipherable, although his pdf notes are decent. Very very hard to understand his accent but midtermfinal very fair. You have to practice but don't bother with lectures.

Absolute worst teacher on the planet. He can't speak English(although what he does say is hilarious since it makes no sense), is a tough grader, has difficult exams and has horrendous notes. Unclear grading schemes. Worst. Don't do it. Just don't.

Comment:
A truly remarkable professor. Every time I entered the classroom, I was shivering with anticipation of the lecture. His various analogies not only made the material much easier to understand but also communicated his down-to-Earth nature, inspiring us. The differential equations may have been ordinary, but he was extraordinary.

Avoid at all costs. If you couldnt already tell all the good responses are sarcastic af. Haven't taken this hard of a class every anywhere. His lectures are pointless. Never once turns his body towards the class, always looking at the board. Never stops writing to allow for questions. Wouldn't even be that bad, but his english is nonexistant.

Comment:
Some of us failed the final, so we have to take the supplemental exam in a couple weeks. Xu said the supplemental would BE HARDER. Because WE FAILED IT THE FIRST TIME, we really need the supplemental to be HARDER. That's the kind of logic this man has. Avoid at all costs.

Simply an amazing professor. Very approachable. Even though some people seem to have some problems with the way the course was run, don't let anything you read here discourage you from choosing to take one of his courses, which will most likely be eye-opening.
