Hi,
No top university will admit you without a GMAT or GRE score. You can reattempt the GRE if the score is not high enough. Typically a score above 310 in GRE and above 650 in GMAT is average. Also remember if you have an excellent profile, brilliant recommendation letters, career growth etc. You may still be accepted with slightly lower test scores, universities check applications holistically.
