How Do I Use These Books Efficiently

I’m going to take my first ACT in 7 weeks and I’m aiming for a 34+ (my SAT score is equivalent to a 31). I’m willing to study for 20+ hours a week to reach my goal

The books I have are

  • The Official Red Book 2016-2017
  • Prep Black Book
  • Barrons ACT 36
  • Princeton Review Cracking the ACT

I’ve been confused about how to start and plan my studying because each book has their own strategies, practice, lessons, etc. and at the same time I want to make sure Im taking enough practice tests throughout the summer but Im not sure when to start and which ones to start with.

TLDR: How should I study using these 4 books

Thank you!
