I got score just above 700 (math 5x and vob 3x). It's not too bad for me. I had prepared for gmat for 3 months and I had to work at day time. The test center is good. I just can not concentrate on vob part after I spent 2.5 hrs on writing and math. It's not a test of intelligence, rather a test of persistence.
