So after taking a couple Manhattan GMAT
practice tests and looking at my percentile after each subsequent question, it seems that my percentile goes up when I get questions right and down when I get questions wrong.
Does this mean I can miss several questions in the beginning, but then just answer all of the remaining questions right to end on a very high percentile?
Likewise, is seems that missing several questions in a row is worse than missing the same number of questions but scattered throughout the test?
Lastly, if I had 4 more questions to go with 4 minutes left, would it be better to answer the first one, guess on the second one, answer the third one, and then finally guess on the last one (assuming 2 minutes on the ones I try to answer) than to answer the first two, and guess on the last two.
Thanks for the help!
