The effectiveness of Princeton Review ultimate ACT prep course?

Hey guys
I have been looking at ACT prep discussions and most people on here recommend self studying for the test. However for me i can’t really focus at home. My current ACT score is a 25 (30 English, 27 Math, 21 reading and 22 for science). Do you think Princeton review’s ultimate act course will bring up my score to a 30? For those who took the course before did it help you improve your reading, math and science scores? My end goal is to achieve a ACT score of 32 and currently i’m planning to take PR act ultimate and then in the summer i will take PR act honors course, so do you guys think that taking these 2 courses will help bring my score up to a 32? What are your reviews for PR act honors because according to the PR site the course guarantee at least a score of 31. For anyone who says that PR isn’t good, could you recommend other act prep courses that help you achieve high scores?

Thank you for your time
