Ok guys

Here I am with the results. I still hope that someone would like to comment on the above questions.
Regarding my first CAT - I'm not sure if the result is good or not, but I think its a good basis, on which I'm going to build in the coming two months. Until know, I've just completed both books:
MGMAT Foundations of GMAT Math and
MGMAT Foundations of GMAT Verbal.
My score breakdown of my first GMATPrep CAT:
Score: 610Quantitative: Q4013 questions incorrectPS: 8 MISTAKES - 1 (exponents), 1 (x,y,xy), 1 (integer k btw. 1 and 10), 1 (Geometry triangle), 1 (integers, exponents), 1 (integers, operations), 1 (y-intercept), 1 (History, English, Maths majors);
DS: 5 MISTAKES - 1 (x<20), 1 (if x=, y=), 1 (apples, peaches), 1 (mean integers), 1 (s and t are different numbers, s+t=0);
Verbal: V3413 questions incorrectSC: 7 MISTAKES
RC: 3 MISTAKES
CR: 3 MISTAKES
And the question is: Which sequence of books to apply from now onwards? I have 7
MGMAT Strategy Guides (all except CR) and just Powerscore's CR Bible

My strategy: Start with the weakest area - one topic at a time (approx. 1 week), take notes, have an
error log for
MGMAT and OG questions; and then move to the next weak area, where I still want to dedicate some hours per day to questions from the previous areas.
How would you structure it?
