Just got a 540 on GMAT, need 600 or more in two weeks.

Hi Juanfer726,

Test Day is a rather specific 'event' - the details are specific and they matter, so you have to train as best as you can for all of them. The more realistic you can make your CATs, the more likely the score results are to be accurate. The more you deviate, the more "inflated" your scores can become - and that's likely what has happened here. By skipping sections, taking the CATs at home, taking them at a different time of day, etc., you weren't properly training for the FULL GMAT 'experience.' As such, this score is likely a bit 'off.'

While it might be tempting to try to take lots of additional CATs at this point, you really shouldn't. You have enough time to take another 1-2 though - and I suggest that you take one more in as realistic a fashion as possible (so take the FULL CAT - with the Essay and IR sections, take it away from your home, at 8am, etc.). The rest of the time should be spent on general practice, review and honing your skills.

GMAT assassins aren't born, they're made,
