I am taking the ACT for the first time in September, and have been practicing quite often. I've been using PR's Cracking the ACT, trying to pick up as many key techniques as I can ( specifically in English). I also purchased the Red Book to use for some practice tests.
My thoughts thus far: it appears to me English and Math are the only sections you can really study for using the books guides. While PR shows how to look at the questions on the English section, its also key to review a lot of Math equations/small theorums and knowing how to answer those problems.
Reading and Science appear the same to me.. The best way to practice these sections is through practice tests, as that is the only way to learn how to use your time and answer the questions.
If you have any personal advice you would like to give me on how to prepare for this tests the next few weeks, it'd be great!
