Seems like everyone has their favorite act book https://www.barnesandnoble.com/w/the-5-lb-book-of-act-practice-problems-manhattan-prep/1120686568
But the Act is a faster test and this was an issue originally with my son. There are tons of problems here. He worked on his weakest and strongest subject. English being weak and math being strong. This really helped him. I would shoot for a 34. More realistic. It’s hard bringing it up when your at 32 and above but definitely can be done. Review all your mistakes and understand why you got something wrong. Good luck.
