I have the following materials with me:
1. Veritas set of strategy guides
2. OG 11 & 12
3. OG Supplements – 1st edition
4. Powerscore GMAT CR Guide
5. MGMAT SC – 4th edition guide
6. MGMATRC – 5th edition guide

How do I strategise my studies? I have gone through all the veritas strategy guides and am in the process of going through the other rc, sc and cr guides. I have taken two practice tests –

1. Manhattan gmat free test – scored 640, Q43 V32 on 12th January
2. Veritas free test – scored 640, Q38 V36 on 19th January

I think the free tests are fairly easy and hence I am expecting some drop in my score when I take MGMAT CAT1 this Saturday. I have access to 5 more MGMAT CATs and of course the most accurate ones – 2 GMAT PREP tests which I plan to take over the course of next 7-8 weeks on every Saturday. I am working full time at present and cannot take leave for preparation. I plan to take my gmat on the day following the weekend so that I get to rest for 2 days before I take the test.

My target score is 750. When should I take GMAT?

How do I proceed with my studies? I will appreciate it somebody tells how much time I need to study and how do I plan my daily studies? Should I do only quant on one day and verbal on the following day etc. I have heard that it is absolutely essential to analyse each and every OG problem to understand what was tested. Should I make a log of each and every problem from OG? Will it be very time consuming if I do so? RC and CR are my weak areas on verbal. Being an engineer I am good at maths but get tricked by a DS question at times.
