GRE 1460 BUT AWA 3.5

HI,
I took my gre in august.I scored 1460.(800Q+660v).
But I got only 3.5 in the analytical writing analysis part :frowning: .Is it that important for students aiming for Ms in Top graduate schools.Would my chances of getting an admission & fellow ship (or assistance ship) will be affected badly.Suggestions r appreciated.
