I had 1100hrs before starting and dudes with no time had better grades than me, my opinion once past primary the rest is all new to everyone...Formation, BFM, ACM, A2A, A2G etc...Need to look at your long term goals as pilot training requires 8 years AFTER you successfully get your wings.

For the record that 1100 got me into F/A-18C's and an exchange tour flying F-15C's with the AF; only thing I would have changed had I known more about it was to try and be a guard baby vice AD.

Good Luck...
