A question regarding studying with the Blue Book

Hello everyone, After studying mostly with Khan Academy and doing practice tests (and a review class over the summer) I have only very recently started implementing my Blue Book. I am taking the test on October 3, so I have realistically only about 2 more weeks to study. There are chapters in the book regarding the material of the test and how to conquer the questions. As a scorer of at least 600 in both writing and reading (except math where I am edging at 620ish where I am focusing mostly), is it even worth allocating my time to reading the notes and other general stuff, or should I spend Most of my time doing the practice tests? Will reading through the chapters ultimately have a significant effect compared with taking practice tests and just reviewing my mistakes? Any input, insight or anecdotes are extremely appreciated, from an anxious studier.
