Thanks all.
My final score - Q49/V35. Verbal score remained same as my exam the day before.
For Quant I just did the OG Main and Additional. I did not study probability at all as it went way over my head.
I took the
E-GMAT Course which I find the Sentence correction section is amazing. In 3 days I went from getting 5/14 correct questions on GMAT Prep 1st Mock in SC to 11/14 correct questions. I did not have much time to study. Just 15 Days. My first mock was 560 (Q42/V27) on
Manhattan Prep. Essentially I went from V27 to V35 because of E-Gmat SC.
Quant was just practice and practice on OG. In total I gave 10 mocks in 15 days. Manhattan/EGMAT Sigma/GMAT Prep.
What I feel is that GMAT is very luck based. Q45 to Q49 within a day just because I got favorable questions was very surprising for me.
