Opinions on my Study Plan please!

Hi everyone,

I just finished a 70hrs classroom style course of both Verbal and Quant. I dont feel this was the best course, but it did help to lay foundations for the test.

So after I went through all the theory, I took a mock exam and scored a 590, Q42 V30. My goal is 700. Although I am a bit disappointed, I plan on taking the official one in March or February so I have time to study.

The materials I have are:
Official GMAT Guide 2019
Official GMAT Quant Review 2019
Officail GMAT Verbal Review 2019
Manhattan Guide: 9 strategy books + Verb and Quant Foundations

I would like to study one strategy book per week, starting at "Guide 1: Fractions" and finishing with "Guide 8: Sentence correction". I would take a mock exam each Sunday until the real test.

The problem I find is that I cant complement the Quant Strategy Guides with the Official Quant Guide because the questions are all mixed up, unlike Verbal which are all separate.
Any recommendations on how to tackle this? I dont mind changing the whole study plan if someone has a better recommendation on how to use these set of books or recommend any additional ones.

Thanks! This forum is very supportive and I am glad I joined.
