This subject definitely isn't easy but the lecturer (Luke) is super helpful and brilliant at explaining things. The tutor I had was kind of hard to communicate with but still pretty good. I'm pretty sure you're allowed to go to extra tutorials if you don't like your tutor. You can get a lot of extra help by going to UPASS or to the feit learning precinct. The final exam is open book but you definitely still need to have a really solid understanding to get a good mark.
