Studying going too slowly?

Hey guys,

So I have begun ramping up my studying for real now. I went through the Manhattan Math Foundations book, and I am mostly though guide 1 of the Manhattan set. I have been reading, doing all the problems at the end of the chapters and then recently doing the recommended OG questions. The issue is that it appears I am a bit slow. Over the course of 3 days of studying I am only on chapter 10 of the first guide.

I am hoping to take the test by 12/15, which is before a long vacation I have slated. That leaves me about 3.5 months to get this done right.

I was wondering how long people spent on each guide book? I was thinking of working until 10/15 on math and then switching to verbal for another 6 weeks. Finally leaving the last two weeks for fine tuning.

Does it make sense to block it off like that? How long should I be looking to spend on each book with that time frame in mind?

Thanks!
