Retake the test that you're not satisfied with. It's like "foolproof" the whole test. But I think it not only boosts your confidence but also makes all the stuff in the test sink up your head. Good luck!
-Review Main Point and MSS questions
-Watch videos for all questions from preptest 44 where there was any uncertainty
-Foolproof all games from PT 44
-Take PT 45 and BR
lol @DumbHollywoodActor it takes as LONG as it takes (and it takes quite long) but you're going about it right!!! It took me 3 - 3.5 months to foolproof whatever I did but I was exceptionally bad at games.
