doing problems over and over again from the OG 11
and 12. I have also DL lots of practice tests online. I had a tutor and he helped me a lot in my math.
I sense two possible errors here. One mistake is to passively practice with the OG too many times. Once you can answer those questions and understand the concepts involved, then it's time to move on to other material. Also, using large amounts of practice tests usually does not accomplish much. There are not that many good-quality practice tests available. The two GMATPrep tests
, along with the six online CAT's from MGMAT and GMATClub Tests
, are considered the most reliable. Beyond that, you step down in quality.
I have been studying for the GMAT for a while now
How long have you studied so far? This might also be an issue. Studying for too long can lead to burnout.
