The best ACT books ???

<p>Ok so I have already used the red book, the online ACT course, and PR. I have also done the free real practice booklet tests.
I did those tests to prepare for the September ACT. I am most likely going to take it again in October. I tried taking a test again, but I remembered the passages and the that's not a good way to study.
Do you guys have any other suggestions...any other helpful books out there?? =(
