I used to score 630-640 on the
MGMAT CATs but the main reason behind my low score was hitting 43-44 in Quant.
MGMAT CAT quant section is really hard, So I wasn't worried about my performance in that section. When I took CAT from mba dot com, I did hit 50 and 49 in the quant section. Moreover before taking mba dot com's CATs, I was very nervous which I thought as a good thing since I would be nervous on the official test day.
But I must confess that I did spend most of my prep time (when it came to practice questions) on quant (I could be wrong but my brain is making me think that way now) since I didn't want to score fewer than Q50 (ego issue since I have a strong maths background). I was satisfied with average verbal performance. Oh well... It kinda backfired.
