Every option, feature by feature
Competitor prices and features were read from each provider’s own public pages on November 10, 2026: PrepScholar’s ACT prep page, The Princeton Review’s ACT Self-Paced, 31+, 34+ and guarantee terms pages, and Mometrix’s online ACT course and ACT Secrets pages. Magoosh’s plan pages, UWorld’s ACT site, Kaplan’s site and act.org blocked automated access on that date, so they are not in this table and none of their numbers is quoted. PrepSolution is our product; we are not affiliated with ACT, PrepScholar, The Princeton Review or Mometrix.
An honest note about PrepScholar and The Princeton Review
PrepScholar assigns four official enhanced ACT tests from the Official ACT Review Guide it mails you, and refunds its course in full if your score does not rise by 4 points. The Princeton Review offers a 14-day free trial and a money-back guarantee with eligibility rules. Both sell live classes or tutoring. PrepSolution’s tests are its own, its guarantee is extra study time rather than cash, and it has no live teaching. Where it differs is price, test count and question volume.
What the PrepSolution ACT system includes
Every figure below comes from the ACT product page, so this page always matches what you can buy.
ACT Explained video course
62 video lessons, 7.1 hours, teaching English, Math, Reading and optional Science one skill at a time for the enhanced ACT.
Every answer option explained
4,400+ practice questions, each explaining the right answer and why every wrong option is wrong.

Rapid Recall flashcards
900+ flashcards for the rules, formulas and facts, to review a few at a time after each lesson.
One-hour diagnostic
A one-hour diagnostic estimates a 1 to 36 score for each section and points you to the lessons to open first.
+3-point score guarantee
If you complete the plan and your official Composite rises by fewer than 3 points, we extend your access free for the same length you bought: 3 more months on a 3-month plan, 6 on a 6-month plan, 12 on a 12-month plan.
Why every answer option is explained on the ACT
Most lost ACT points come from the same traps, repeated. Every PrepSolution question explains why each wrong option is wrong, so a missed question becomes a lesson, not a guess. Every question is written by PrepSolution, not taken from an official test.
Every option explained
Each question explains the correct choice and why each wrong option fails.
Scored like the real test
Full-length tests return a Composite and a 1 to 36 score for each section.
