GMAT Strategy

I started studying for GMAT in August. First Kaplan diagonstic was... 350. Then I worked at it and reached 600s in Kaplan. Three weeks ago I discovered this website and started the OG 11. I have taken a few intense work trip that have interrupted my studies, so I'd say I studied for about 3 months total. I have another major trip coming up on Nov 14. So I scheduled my test for Nov 13, 2 pm. I still have 400 more tasks to go in OG and probably 40 flashcard to make, but I start losing it - I scream at the book when get it wrong, and just even though my employer has been patient with me allocating 4 - 6 hours a day to GMAT last 2 weeks, I don't think it can last (also the office is moving same days as my trip). Last CAT2 I had 710. I did guess a few sucessfully though. QUESTION: should I go for it and take it on Nov 13, or postpone it for another 2-3 weeks?

Thank you guys!

Please answer, someone!

Thank you Guest.
I'm studying like a mad man, and thinking the same. I'll do 6-8 hours each day this coming week, 3 more cats, and then stare at the flash cards all sunday, sleep, eat, watch a movie on monday, and go take it up the .. on tuesday, the 13th. More advice and strategies for my last week are very appreciated guys. C'mon help!

Aahhh! Allright - that's a good one. Thank you
