I've sat in on demo classes for every major ACT prep course over the past three years. The honest pattern: the expensive ones aren't 4x better than the free ones — they're 1.2x better with a lot more accountability. Whether that's worth $1,800 depends on whether you'll do the work without it.

1. Khan Academy ACT — best free structured course
Khan Academy partnered with the ACT in 2023 for free official prep. Coverage is solid for English, Math, and Reading. Science is thinner. UI is from another era. Best paired with AceNotes for active recall practice.
2. AceNotes — best free active-recall layer
Not technically a course — it's the study app most students pair with whatever course they pick. 100 ACT-specific study sets, AI tutor, full-length pacing drills, all on the free tier. The piece every paid course makes you upgrade to get.
3. Magoosh ACT — best low-cost paid course
$129 for 12 months of access. Video lessons + 700 practice questions + 3 full-length tests. The +4 score guarantee is real but requires documented baseline + completion of 80% of the course. Best value-per-dollar of any paid option.
4. PrepScholar ACT — best for students who need structure
$397 for a fully adaptive curriculum. The platform adjusts your study plan based on your weak areas. Best for students who need to be told exactly what to study tomorrow. Less useful if you can self-direct.
5. Princeton Review Self-Paced — solid baseline course
$499 for self-paced video instruction. Princeton Review's content is well-tested. The self-paced version skips the live instruction but keeps all the practice material.
6. Kaplan ACT Live Online — best live group instruction
$799 for ~36 hours of live online classes. Smaller groups (15–25 students) than Princeton Review. Instructors are competent. The score guarantee is meaningful if you complete homework.
7. Princeton Review Live Online — bigger budget, broader reach
$1,099 for the same content as Kaplan but with TPR's brand and slightly better materials. Larger class sizes (often 30+).
8. Princeton Review Ultimate Class — top of the boxed-course range
$1,799 for live classes plus dedicated office hours and unlimited tutor access. Worth it only if you'll use the office hours.
9. Compass Prep — best 1-on-1 (region-specific)
$200–300/hour for individual tutoring. Compass tutors are vetted and the curriculum is custom. Best for students above a 28 baseline who need section-specific work, not whole-course instruction. Available in major U.S. metros only.
10. Revolution Prep / Inspirica / AJ Tutoring — premium private
$3,500+ for full-package private tutoring. The instructors are elite. The marginal score gain over Compass is small. Worth it if budget isn't the constraint and you want a high-touch handoff.
