I took two diagnostics and scored a depressing 143 on each


My target is 168 for the schools I want to get into. The testmasters coarse is really good but I don't know if I can get up to 168 (tall order) in 3 months time. The testmasters HW is brutal but well structured which is what I needed to get going. My testmasters course ends in May after which I will just be taking timed practice tests until the June exam.
Is 3 months enough time? I'm guessing it is not. October seems more realistic. Thoughts?
