First attempt 580(Q44,V26) Second attempt 640(Q49,V28) no 700 yet

Hello experts

I gave my first attempt on feb18 2015 and scored a low 580. I was completely lost and disappointed. So whatever I regained my self confidence,joined E-GMAT online course and started preparing for my second attempt. My first attempt enemy was timing. I tried hard and improve my timing on CR and RC. I could only manage to complete the e-gmat SC section. I prepared sets of 15 CR and 15 SC and 4 RC passages. I worked on my timing well. I used the MGMAT CATS and scores always used to hover around 670-680 range. After 2months of hard work i booked my test date (may14 2015).

TEST DAY

AWA IR and QUANT were just a breeze completed them without any pressure. Took the complete 8 minute break and was getting ready for verbal saying to myself okay do the best you can with what you have. I started my verbal section initial 5 or may be 6 question were quite simple and then the test kept throwing at me a lot of CR EVALUATE questions. I was like errrrrr . And RC didn't go well either. Finally pressed the submit button and bam 640 Q49 V 28. I was happy that at least my quant improved but verbal just 2 point improvement.I just cannot pin point what my prep mistakes were.

So with my TOEFL score of 96 and GMAT 640 I decided to apply to some B-schools for an MSF program and got accepted to UT dallas Jindal school of management. This was the only school that I applied to because I missed the deadlines of most other schools. BUT my goal is to get into UT AUSTIN MCCOMBS SCHOOL OF BUSINESS and pursue a career in finance for which i need a GMAT score of 700.

So experts please help me to reach my target score.
