Somehow I differ with Neo2000,
I have checked with 6 guys 3 of them US-citizen and 3 of them visa/ead holders in US
for 3 US-Citizens quant was as easy as even getting a repeat from
OG 11 !
for the 3 'desi's quant said "who's your daddy ?"
it's a different story that 2 out of those 3
desis still went to score 49/50 in qa :-)
But the point is : Whatever the situation, there is no escape; either you break GMAT or GMAT will break you.
