I just did a test on PP2 this morning, my first mock test, with a terrible score, 149+159.
make a summary.
First, vacabulary, not only comprehension, but reaction time, the faster the better. Second, time control, even the quantitive test, which I may feel more comfortable with, had one question left blank in the 5th section. Third, test environment adaptation, I don't feel very comfortable with the test environment.
