Both tests are now shorter and computer-based, so prep that uses outdated paper formats can hurt more than help. Here are 8 strong options and how to choose.
What changed — and why it matters for prep
The SAT is fully digital and adaptive, meaning the second module's difficulty adjusts to your teen's first-module performance. The ACT has also moved to a shorter, largely digital format with an optional science section on many test dates. Any course you pick should train on the current formats, not legacy paper tests.
1. Best free option: Khan Academy (SAT) + official ACT prep
Khan Academy's Official Digital SAT prep is free, built with the College Board, and uses the real Bluebook testing interface. For the ACT, the official ACT online prep and free practice tests are the closest to the real thing. Unbeatable value — the main gap is no live instructor to keep a teen accountable.
2. Best overall paid course: Princeton Review
Comprehensive courses with score guarantees, thousands of practice questions, and options from self-paced to live online and private tutoring. Strong for families who want structure and a money-back or improvement guarantee, though it's among the pricier mainstream options.
3. Best for score guarantees: Kaplan
Kaplan offers a "higher score guarantee" and a large question bank, live online classes, and on-demand video. Its Qbank and full-length adaptive practice tests are a strength. Similar tier to Princeton Review — compare current pricing and guarantee terms.
4. Best budget self-paced: UWorld
Known for high-quality questions with detailed explanations at a lower price than full course providers. Ideal for a motivated, self-directed student who mainly needs realistic practice and clear answer rationales rather than live teaching.
5. Best adaptive/AI-driven: PrepScholar
Uses an adaptive engine that diagnoses weaknesses and customizes a study plan, with a score-improvement guarantee. Good for teens who study independently and benefit from a program that targets their specific gaps automatically.
6. Best premium tutoring: Compass Education Group / private tutors
One-on-one tutoring gives the highest ceiling for score gains and is the most personalized — and the most expensive. Best for students chasing top-tier scores or who struggle with self-motivation. Vet tutors for experience with the current digital formats.
7. Best for busy students: On-demand video (e.g., SuperTutorTV, Magoosh)
Flexible, mobile-friendly video lessons and practice for teens juggling sports and activities. Lower cost and self-paced, with less accountability than a scheduled class. Magoosh in particular is a low-cost, well-reviewed option for independent learners.
8. Best local option: high school or community classes
Many high schools, libraries, and community centers offer low-cost prep taught by local educators. Convenient and inexpensive, with in-person accountability — quality varies by instructor, so ask about materials and whether they use current test formats.
How to choose the right course
- Take a free diagnostic first. A full-length practice SAT and ACT reveals which test your teen naturally scores better on — many students should focus on just one.
- Match the format to your teen. Self-motivated learners thrive with self-paced/AI tools; those who need structure do better with live classes or tutoring.
- Insist on current-format practice. Confirm the course uses the digital SAT (Bluebook-style) and the current ACT — not old paper tests.
- Set a target score and timeline. Give at least 2–3 months and a realistic goal based on the diagnostic and the colleges on the list.
- Weigh cost vs. accountability. Free tools work if your teen is disciplined; paid classes and tutoring mostly buy structure, guidance, and accountability.
The bottom line
Start free with Khan Academy and official ACT prep plus a diagnostic to pick the right test. If your teen needs more structure or a bigger jump, Princeton Review or Kaplan offer full courses with guarantees, UWorld and Magoosh deliver strong practice on a budget, and private tutoring gives the highest ceiling for a price. The best course is the one your teen will actually finish — on the current digital formats.
