ACT reading practice

I’m taking the ACT again in October and I need to get at least a 31 on the reading section (all of the sections really). What are some good resources that I can use within the next 2.5 weeks. I have been practicing but I have finally narrowed down my problem in reading and I really need to nail it down. So my question is: What are good and accurate resources that I can use to practice for the reading section? Also, what are the oldest tests that I can still use.
I already have the Red Book (only one test left), I’ve been on CrackACT and gotten a few tests from them, using PrepScholar ACT online, NOT going to use McgrawHill 10 ACT exams because they are not accurate…
