Thanks for the tips guys.
I feel quite reassured now. Unfortunately i haven't maintained any error logs but i do have a list of important math concepts that i keep reviewing every now and then.
Just to put things in perspective, i have created a focused study plan for the next 9 days to focus on my weak areas (quant) and strengthen Verbal. It is just to keep me motivated till GMAT Day
I will try and extract the maximum out of a limited set of questions in the next 9 days.
Days 1 to 5 (Concept reinforcement) - Timed drills of 25 questions each covering PS, DS, CR and SC and analysis of each question from the GMAT Prep documents that i had mentioned.
Days 6,7,8: GMAT Prep Test 1 (twice) and GMAT Prep 2 (once) and analysis of tests (Do AWA in all 3 tests); review
error log (great idea by the way) of questions done in days 1 to 5 along with some essential Math and SC Rules.
Day 9: Relax, watch a movie and pray

Day 10: Tame the GMAT
