GMAT Strategy

If i take GMATPrep test1 multiple times (>3) will i see repeat questions on test 2.

I want to save test2 for later on.

1) i think this is in wrong forum section

2) i think GMATPrep 1 and GMATPrep 2 are two different bin selections. they use two different question databases

You'll see repeats in GMATPrep if taken many times (2+)
I'd suggest you to take scores of GMATPrep 1 & 2 seriously for first attempt only.
You can retake them but should not trust its score in latter practice as you'd find some familiar questions. Instead use them to check your endurance & exhaust unseen questions.

(btw, moved to strategy section.)
