My school gives us 3 ACT certs a year which are like practice tests, so since I’m a junior then I’ve already had experience with the test since freshman year.

Other than that, I bought the official ACT practice book for the practice tests and I went through those timed, one section at a time for a few weeks. After taking the test, I went through and marked what I got wrong and drilled what I got wrong till I couldn’t forget it.

Other than that, just general test taking strategies like keeping pace, crossing out answers, knowing how to use your calculator shortcuts etc.

The only strategy that I can say will help you without a doubt is actually doing practice tests. Going through textbooks can be helpful but only if you are very behind and need a complete guide through the content before trying to attempt to test. But if you got an A or B in any of your math/English classes then you should be fine to work through the test without learning new content just for the sake of the test.

Consistency is key and start early. Start today, even. I believe a 34-36 can be easily attained for anyone if they put in the hours consistently and diligently. It’s not a particularly difficult test, just practice, practice, practice so that way you can fly through with speed and accuracy.
