Even though I didn't meet many GWD in real test, but I was much sure my total correct rate is above 80%. I just got v31. I am thinking I made too many errors in the first ten questions. According to LZ't theory, I just made mess the high-score qustions.
whether we should finish all the questions or just finnish those we are sure? According to the theory of LZ, if we don't answer any question, our score would be 400, that's good enough for most of XDJM?
If you do not answer some questions, the system will automatically judge all your no answer questions be to wrong. In the GMATPREP, ETS says:"you will always find your score higher if you finish all the questions in time. So care about the time, and try to answer every of them.
