Here is how I stand:

Taking the gmat on 13 nov (roughly 6 weeks plus)
Been away from studying for over 10yrs and awefully rusty(had to try and deduce the area of a triangle and skipped all coordinate geom and perm/comb probs)
Took 2 manahattan tests on consequtive days and got the following
Test 1 : Q(44,73%) V(35, 77%) overall (650, 84%)
Test 2 : Q(45, 77%) V(32, 67%) overall (630, 79%)

I have the following and plan to be reading from:
Kaplan Comprehensive programme (no cd with book)
Kaplan 800
OG 11, orange one.
Manhattan sentence correction.

Managing to finish the lot is a big challenge for me as I am finding it very tough to sit and study. Taking that into consideration, would you suggest I try to study any other books? Should I get the green and purple (verbal and quant) OG11 books or any other books?

Also could anybody tell me where to get the KAPLAN CATs. My plan is to take Manhattan tests in week 1,2,3,4; take Kaplan tests in week 2,3,4,5 or week 4,5(depending on the number of KAP tests); and gmat tests in week 5 and 6.

Is 720 - 750 a realistic target or am just shooting for the stars?????

Any suggestions would be greatly appriciated.
