Do not overestimate GMAT test prep results.
It goes without saying that you need to leave enough time and plan effectively during GMAT preparation.
Even if you don’t necessarily need a 700+ GMAT score for your MBA application – maybe only 500 or 600 – it is still wise to overshoot during preparation in order to more or less safely reach your required score.
Redoing a prep-test exposes you to a greater volume of questions.
