Hi all. I'm totally confused and stressed about the GMAT. Any advice is greatly appreciated.
I've been studying for the GMAT since mid-October. I wrote the official exam on January 2nd, did poorly, and so I'm scheduled to write again just over 31 days later on February 7th.
History:
15-Dec-07 GMAT PREP 1 Q? V? T560-- didn't finish either section
22-Dec-07 GMAT Written TestQ40 V39 T670
24-Dec-07 GMAT Written TestQ45 V39 T660
30-Dec-07 GMAT Written TestQ45 V37 T650
01-Jan-08 GMAT PREP 2 Q43 V37 T660-- day before official exam
02-Jan-08 GMAT Official Q42 V30 T590-- exhaused by the time I got to verbal
Today GMAT PREP 1 Q42 V35 T640-- today after fresh reinstall (removal of previous exam folder) - one month after official exam and more math/verbal studying.
I'm super confused, b/c I didn't finish the exam today (neither section). I decided admist the stress and sweating of taking the prep exam today that I would pospone the official exam for another couple of months until April, because duing today's prep, I was sure I bombed severly. It doesn't make any sense to me, on the verbal section I had to guess on the last 10 questions and I didn't even get to enter a response for the last two! So, obviously I thought I did horrible. I would have cancelled my scores, if I felt that way during the real exam. Then, I end up with a mark of a 640

It doesn't make any sense to me, as I would expect severe penalties for guessing and not completing the exam, but to still end up with a 640.

I think a 640 is quite good for not finishing either section.
I'm aiming for a 690+ and I am scheduled to write the official exam in exactly 72 hours.

Do you think it's possible? And, if so, how should I prepare over the next three days?
Timing is a major issue for me, as I always have to guess on the last 1 or 2 questions, but not 10. I feel like my verbal and math skills have improved over the last month, but I'm taking way too long to finish each question. There were very few repetitions on test I did today and the previous Prep 1 (approximately 6 weeks ago), one math question (which I got wrong again), and a couple of verbal.
Work is VERY busy for me, so I don't expect to be able to get another morning off until at least mid-April to be able to write the exam. So, it's either this Thursday, or mid-April.
Sorry for the long post. Any advice is greatly appreciated.
