GMAT Strategy

hi all, i need to know whether my strategy so far has been right and how can I improve it
Verbal resources
1. Verbal :MGMAT SC, CR, RC guides -> all studied for concepts and worked on 50% of OG 12 and Verbal review 12 questions
2. Quant:
Topics done :
Word Translations + corresponding OG 11 probs
Geometry + corr. OG 11 probs
Topics pending:
Inequalities, VICs
Number properties
Fractions, decimals ( all MGMAT guides)

i tend to study a particular topic and then solve the OG / Quant Review questions after that.
Can someone recommend any more books from which i need to solve practise problems?

i have the following resources at hand for the questions
1. OG 12, Verbal Review 12 , Quant Review 12
2. OG 11, Quant Review 11
3. Kaplan 800
4. Kaplan Verbal Workbook ( 2009 edition)

Please tell me if i need to practise any more problems apart from this material that i have.
please note that i am 10 weeks away from my test and the topics i have covered so far are listed above

I intend to do the MGMAT practise tests once i have devoured all the concepts for Quant.
Is solving from OG at the end of each topic a good idea? or should i take it big bang and read ALL guides / concepts
and then attack the entire OG set?

Please help me as i am having sleepless nights over the same.
P.S ; i work on weekdays so i am able to study 3 hours daily and upto 6 hours on weekends ( mostly boredom kicks in beyond 6 hours)

Please Help
