Should I retake the ACT? And if so, how can I improve my score?

Hey everyone,
I’ve taken the ACT twice already.
The first time I got a 31: 30 in English, 31 in Science, 35 in Math, and 26 in Reading.
The second time I got a 32: 36 in English, 36 in Math, 31 in Science, and 25 in Reading.
I’m extremely confident in English and Math and can consistently get 34-36 on practice tests. Science i’m alright at but for whatever reason I’m terrible at the Reading section. I always run out of time with a passage+ to go. I’ve tried all the different strategies but I just can’t finish in time. My reading isn’t the issue (I don’t think) because I got a 5 on AP literature and composition this past school year.
I have some safety schools, but I want to know if a 32 gives me a chance at getting into Stanford, UPenn, Northwestern, or UBerkley. Thanks so much everyone!! (I know other factors besides ACT go into an admission decision but I want to know how a 32 is assuming everything else is up to par)

The reading and math sections are the most important. Good luck.

if you have the time and the money, why not?
