Thanks for the check . Yes verbal (33) seemed in range, but Quant in test4 (41)and test5 (39) i felt pretty hard and i maked around 5 700-800 questions correctly and then very hard questions start to come and marked all of them wrong

around 4-5 , hence this drop .
Esp in CAT5 i simple couldnt manage time and i missed to mark 1 question.Thats the reason i can think of for the very low score.
That got me worried and did CAT6 with vengence, then into 6th math question, site was down then 2 mins later when i resumed the test, it started me of with 7th question but gave me 10 minutes extra..so had plenty of time for CAT6 Quant and killed the math, i never score 48 in manhattan tests ..
