This course is one of the toughest in second year. I found the first half of the course extremely easy compared to the second half. Mahmoodi is a good professor who provides practice solutions in his tutorials which he works through, but he can ramble a bit and not explain things very well. His tests are on the difficult side (the average of the second midterm was less than 50). The good thing is he curves generously.

Do the practice problems and don't fall too far behind, even if you think it's easy.
