Hi shinichikudo,
I’m happy to provide some advice regarding your GMAT; however I’d first like to learn more about your situation with the GMAT. I have some questions:
1) How many practice GMATs have you taken? Please list the dates on which you’ve taken any practice GMATs, the total scores, and the quant, verbal, and IR scores, as well as how you were feeling while taking the tests. Also, please tell me where these tests came from (ex: mba.com).
2) Please describe how you have been studying. For many hours a day and for how many months?
3) To what programs will you be applying? What are the deadlines for these programs?
4) By when would you LIKE to take the GMAT? By when MUST you take the GMAT?
5) How many hours a day, on average, can you study between now and your next GMAT?
6) What is your GMAT score goal?
Once I learn a bit more about you, I can provide some detailed advice.
