I’m taking the ACT in March through my school and don’t know which prep to use. I scored a 31 C (31 E, 30 M, 30 R, 31 S) by using the Princeton book, but I honestly don’t know how I scored so well. I would like to bring my score up to a 33 for schools like Duke or Georgetown but I do not know how to by myself. Any suggestions?
PS. the scores are from this December test

I think the Princeton Review has a premium version, specifically geared for students who want to get 33-36, you might want to check that out
