Hello,
I am finishing up my 4yr of clinical electives. I have taken Step 1, CK, and will take CS by the end of June. I however, will only match for 2017 and would like to take Step 3 before beginning residency.

Any advice on what do use for preparation? Besides U-world, is there a book I should be using/referencing or just going off my knowledge from the previous exams?

Thanks in advance!!!
