GMAT Strategy

The goods: I ordered all 8 Manhattan Study Guides, and the 1
year access to the CAD's. I also ordered the OG Quant / Verb
and the OG 12th Edition. I downloaded the free Flashcards
and the free GMAT prep software.

The plan: I plan on going through all 8 Manhattan Study
Guides (2 hours minimum per day / 6 days a week). After this I
plan on starting my 1st practice tests (moving to 7 days
a week with tests on Sunday). After these study guides
are complete I will be going over the OG Quant / Verb, and
doing more practice questions from the 12th edition. I'm
going to be reading the flashcards during spare time
(I'm a senior in college with 1 hour gaps in between classes
and whatnot). I plan on starting the GMATPrep Practice Tests
during the 5th Manhattan prac. exam(2 a week). I have a large
amount of time and would like to set myself up for a
good score.

My question is, any thoughts or recommendations to my
strategy. Any advice is welcomed.

Thanks in advance!
