Yes BTG will help. I've known you since our school years and I had no clue you wanted to take the GMAT. I know you're a genius Bhagre and you can work really hard, but the GMAT is a different beast.
Firstly, contact me for my notes (which once completed would be up on BTG). They'll get you atleast 40 above on the verbal and 51 or atleast as close to it as humanly possible on the quant section.
Secondly, seems to me like you are having timing problems. You prepared using the OG and I am sure some other resources, but you should definitely go through the timing related articles and strategies on BTG. A timing strategy that worked for me and got me from 680(on the real thing and 700 in practice) to 730-750 (in practice, my real thing is in july, my problem was timing):
I just keep a normal pace in the beginning. Then, I set 'laps' for myself. I got this off off BTG somewhere too. Laps on verbal look like 'when 60 minutes are left, I should have 31 questions left','at 50 minutes questions left or whatever is comfortable' and so on till the point where 20 minutes are left. I never gamble after that point with time because you loose way too many points if you get a bunch of questions wrong in quick succession. I alternate (which means I solve one question and intelligently guess on the next one and then I solve the Q and so on, till a comfortable number of questions are left).
So your situation of doing 15 (mostly wrong questions) in the last 10 minutes would not happen.
And Q 49 is good but not great. I have some support for that too.
Please post how you prepared, what were your scores in practice and everything else on the "I just beat the GMAT" forum, so we know where to improve. Hope this helped.
