ARE Study Prep - US

I’m not really the best test taker, so looking for any tips on how to study and pass all 6 exams. I’ve tried black spectacle but didn’t like the lecture format. I’ve heard Amber Book is good so might get on that! Wanting to take PCM and PJM together. I’ve created a study schedule and should be done studying for both exams in 6 weeks - this includes practice exams. Is 6 weeks reasonable?

Open to any study formats that worked for people.
