Good luck.
I used the AFE books, information is very easy to understand with diagrams etc. but I noticed a couple of things that were in my exams which were nowhere to be seen in the books. Either that or that was me being thick
I have heard that the Trevor Thom books are good, albeit the information is presented in a much drier manner. try speaking to your instructors, they should point you in the right direction.
