On my most recent Manhattan GMAT
CAT (12/09/12) I scored 540 (Q36 V29)
Since I was behind on Quant I studied Math for the next two weeks only and very very little verbal. Then I took a GMAC GMAT on December 22nd and scored 530 (Q41 V21).
Good news was that since I studied only math for two weeks, I improved 5 points on Quant. Since my goal was 600 on 1st try, I thought that since I have 41 in Quant and 29 in verbal from my Manhattan test, I will study both subjects for few days and take the test on my scheduled date which was December 28th. So I did non stop practice problems from the OG guides for both verbal and quant and I was doing very well to score 600. And then I took the official test on December 28.
The result was highly disappointing. I only scored 430 (Q29 V21)
Can someone provide some advice on what could have went wrong and what can I do to improve? There was no surprise on test day. I mean all the questions in Quant were similar to what I have seen in practice questions or in Manhattan materials. Don't know what happened. Can you offer some words of encouragement along with tips to improve from this heartbreaking score. Looking forward to your reply.
