Comment:

Tends to go off topic nearly every lecture. Knows and understands material really well, however, not the greatest at explaining. Should've spent more times running through examples rather than ranting about Bahen.

Goes off topic every now and then on things that aren't related to the course. Office hours are alright if you can get to him. Tutorials are probably better for getting a grasp on material.

I found his online lectures to be extemely clear and helpful, and Im taking him again for APS163 this semester. His in class MAT188 lectures are frusterating as he goes off topic, I may end up stopping attending his in class-lectures.

Comment:

No help for students outside of his packed 1 hour office hour, says he will look at Piazza, the online forum used, but checks once a month. Insanely long times to mark (Still waiting over 2 months for our first problem set, along with problem set 2,3 and test 2 mark ). I do not recommend taking a class with him.

Shai's teaching is very inspirational. As for the difficulty, it's actually easier than my eco206 class.

Comment:

I'd like to say despite how the summer course was ran, he was a wonderful and phenomenal professor. He really showed me the true spirit of mathematical thinking (and actually got me of all people to like it). The course itself though isn't supposed to be too hard (or interesting for that matter), but Shai defied all of that. Would take him again!

Comment:

Barely teaches anything then makes overly difficult term tests and assignments. Little to no practice or preparation given for them. Tutorial and quiz material is ahead of the lectures or he teaches on the day of. ONE office hour for two big classes. Rarely comes on Piazza. Doesn't respond to his emails. Still don't have Problem Set 1 marks.

Comment:

"I am English Major", he said. He work for Mathmathtica Department, but teach CSC165. Useless lecture, so much irrevalent boring story. So many mistakes on problem set. Waste your tuition. The exam is extremely hard, he believes that most people should not be able to complete all the question. DO NOT TAKE HIS COURSE. ITS JUST BAD.

Comment:

If you're thinking about taking his class -- stop, do not enroll. In summary: 1) Lectures are complete disorganized and unrelated to the course content. 2) Shai has little to none time to support students. 3) No marks are posted until almost the final exam. 4) Tutorials are useless. 5) Problem Sets and Quizzes are full of errors.

Comment:

Very useless lectures, always telling some useless stories, and run out of the topic every single lecture. Used to post the wrong answer for a question multiple times. Marking is extremely slow, we haven't get back the first midterm even we are going to write the second midterm. We don't even receive first problem set up to second one is due.

Comment:

He recommanded to all students to sign up to Piazza(the discussion board). In fact, he showed up to the discussion board in the first month only so there are many questions you posted on the discussion board left not answered. In his lectures, he often got off topics and talked something not important, but tests and assignments are harder.

Comment:

So inspirational professor. His lectures are crystal-clear and he still somehow makes time to explain stuff in a very interesting, unorthodox way. Personally, I love his style of teaching.
