ritula, first of all relax. GMATPREP haven't shown me more than 640 after 1st attempt. But I got 690. To be frank I ordered the second test next day

. 1 week before the G-day I got 560 and was totally crashed for 2 days but I couldn't postpone without loosing a full amount of money so I decided just to practice. Don't care. If you are calm in that day you'll bomb the test. My suggestion is to practice pacing a full CATs and that's all. Repeat all basics of Q&V then re-solve all wrong questions following your log. After kick all gmat's bullshit 1-2 days before the date, sleep well, and go to have fun. God tells good luck to crazy human
