Free cheat sheet and 7-day study plan

Two PDFs, free after you give your email. These and the sample test are the only items on this site you can download; the paid kit is online access, view-only.

How to use the sample

Set a timer for 35 minutes. Answer the closed-book questions from memory; for the open-book ones, say which document and section you would open before you choose. Afterwards read the explanation for every question, including the ones you got right: the reasoning is where the learning is.

All questions are original and no exam content is reproduced.
