sabbah is a veryy good teacher. if you do all his worksheets, you'll be more than ready for the tests and you'll do well in the class

I had him for Linear Algebra, honestly his classes are pretty understanable and he explains really well. But his exams are way more different than the exercices he gives in class, which makes his exam pretty tough.

He is a very decent teacher and you should take him if you have the chance.

I had Isaac Sabbah for the winter semester of 2022 for calculus 2 and his class is super organized. Always make sure to go to class and to do his worksheets because they really help. I used to hate math but he always made the material understandable and his notes were excellent. If you go to class, you'll walk out knowing so much that you don't even need to refer to external sources for help. My suggestion is to do the worksheets right after class or on the day of so you have questions prepared for him. Do not be shy to ask him anything, I have the dumbest questions and he still answered them with no judgement. Loved this teacher and definitely pushed me towards achieving a career with math involved. :)

My experience with this class was horrible. In class, he explains all the easy stuff and the basics amazingly, but does not show how to do medium/ hard questions! His exams are level difficulty 1000 so how are we supposed to do them if he's only taught the easy stuff?? He gives soooo many worksheets that you NEED to do in order to even pass this class. If there's even one thing unclear, u need to figure it out fast bc it will come back to haunt you. Also, we rushed way too fast into the course that we had a whole month left of revision/cancelled classes. HORRIBLE. A real nightmare.
