Incorporating different materials, especially Manhattan 5lb

I take the test in 24 days, and I am targeting 165Q. I am not finding time to incorporate the 5lb. into my studies as I am struggling to even complete the Prepswift daily plans as things stand.

Is the 5 lb. still critical if I wish to score that high? How should I combine it with Greg’s videos, tests and quizzes? I would especially love to hear from you if you moved from a sub-150Q on a diagnostic to 160+Q on the actual test or practice tests, regardless of the materials you used.

For some context,

  1. I’m on Week 1 Day 3 of the 1-month plan; I did “Getting Started”.

  2. I scored 148Q and 162V on Magoosh’s diagnostic (yeah, not official) about two weeks ago; I’ll take a PP this weekend.

  3. I have the ETS OG, Old Book, and Official Verbal and Quant Strategies books too.

How should I go about it all?
