Im starting to self study both AP micro and AP macro this semester (using my lunch period to self-study) and have a few questions.

A: Is it possible for me to allot 40 mins each day every day of the week to self studying AP Micro and AP Macro and expect to receive 5s on both?

B: Would it be better to prepare with 1 textbook and like 1 review book or lots of review books?

Thanks in advance!

Update: Iordered the 7th edition principles of economics by Mankiw. Would this better prepare me for the exams rather than using the review books?
