In terms of whats making it hard for particular students is that most year the tests are JUST like the previous years ones (they give you tests from last year). But this year, the questions seem different from what we've been told to study/practice, or have seen. So a lot of people who aren't already great with math - again, like myself - aren't doing the best. Like the second test, for example, was extremely poor for a lot of people because it was entirely different from what we're used to. But overall, they do a LOT to help you - there's tutorial, there's the course package with assignments, textbook question numbers, etc. Lovric is supposed to be really good especially.
I have Clements right now - she's really helpful during tutorials.
They drop 1 of the 4 tests though!
If you do your work, attend lectures, you should do great! Overall, the material isnt hard to grasp, we just need a little motivation
