Thanks for the very prompt response bb. You are right in saying that few questions from OG 10 overlap with OG 11. Thats the first thing that made me look at OG 10 and wonder why people prepping don't practice from PG 10. In fact, I haven't found a single instance documented anywhere on the web where anyone prepping to give GMAT in next few months is using OG 10.
As far as strategies and foundations in maths and verbal are concerned, I have superficially read through the Cracking the GMAT book (PR). I didn't find it good enough. I am hoping to develop my strategies through practicing as many questions as I can. Also, I am aware of the basic concepts in maths and verbal. Where I falter is the application of these concepts in questions. Therefore, again, I am banking on practicing actual questions to actually conquer this. Also, through the thorough analysis of the questions, I should come to know which fundamentals I need to brush again. Then, I can just revisit the fundamentals of that particular topic. Does this make sense?
Based on this, I have also created a detailed study plan for the next 50 days (attached within). Your take on it?
Thanks in advance for your inputs

P.S.: The calendar template I have used for my plan is picked up from this forum only. I found it really helpful. My thanks to the creator
