Since early March, I rigorously studied for the ACT at the pace of one practice test out of the Red Book or from Princeton Review's ACT book per week. I progressed from a 30 composite score to a 33. I carefully look at the answer and explanations to make sure I know why I missed questions. I also pinpoint trouble spots and focus on them. Do you think this is a good plan by doing one test a week or should I slow down knowing I improved?
