Summer study plan to improve to 32+

I am planning to re-take the ACT on September 12 to improve my previous score of 29 up to at least a 32. The main things I need to improve on are the Science and Math tests. My English and Reading scores were both 32’s last time but my Math was a 28 and my Science was an abysmal 25. I have about two and a half months to study for the next exam (September 12) and improve my science and math scores. What do you recommend that I do on a daily basis to improve these scores? I currently been reading through my ACT Elite 36 and Real ACT Prep Guide books everyday for info on the Science and Math sections and spending about 30mins to an hour. Anything I should do differently? My biggest problem was not having enough time so any tips on improving speed while retaining accuracy are greatly appreciated.
