Our Methodology
TestPrepData produces guidance grounded in primary sources. Every article begins with official documentation from the College Board and ACT, including published test specifications, released practice materials, scoring data, and official policy on registration, retakes, and score reporting.

We supplement official materials with the perspective of experienced tutors and test preparation professionals who work with students directly. Their input informs how we frame study timelines, prioritize content areas, and address the practical questions students and parents face.

Its self-paced, online course was fully rebuilt for the Enhanced ACT and is paired with one of the largest high-quality practice libraries in its class with a fully adaptive study path. Additionally, PrepScholar stands behind its product with a 4-point score guarantee, which is one of the strongest among self-paced programs.
As for other top ACT prep courses, Magoosh remains a strong low-cost pick for self-directed students, Princeton Review's ACT 31+ course has a lot of live-class options for students who want the structure of live instruction, and C2 Education is a solid option for families who prefer in-person tutoring.
ACT prep options — including ACT online programs — span the same price range as SAT prep, ranging from free platforms to four- and five-figure private tutoring packages. To narrow the field down to the strongest choices, we compared each program’s format, pricing, score guarantees, and practice content against the current Enhanced ACT.

Methodology: How These Courses Were Evaluated
Each of the best online ACT prep courses on this list was assessed on:
The Top ACT Prep Programs, Ranked
#1: PrepScholar: The Best ACT Prep Course 2026 Overall
PrepScholar is our top-ranked choice for a quality and affordable ACT prep course. The company’s flagship course offering, Complete Online ACT Prep, costs $397, comes with a 5-day free trial, and has a 4-point score guarantee. With this package, you get a personalized study plan, 90+ skill lessons covering every Math, English, and Reading topic (as well as the optional Science section) that appears on the ACT, 4 full-length practice exams, 3,000+ practice questions, totaling over 60 hours of instructional content.
An adaptive learning platform analyzes your performance and adjusts your study path as you go, so practice stays targeted to what will actually boost your score.
While other programs simply tweaked their ACT prep courses, PrepScholar rebuilt Complete Online ACT Prep from scratch for the new, Enhanced ACT. From the 54 refreshed skill lessons to updated practice questions to your personalized study plan, all of PrepScholar’s ACT prep content prepares you for success. As an added bonus, PrepScholar also comes out as the best ACT prep course for the money.
Best for: PrepScholar’s online ACT prep program is best for students aiming for a meaningful score jump on the ACT on a short prep timeline. Between its structured, adaptive, self-paced format and generous score guarantee, students can feel confident they’re not throwing money at a course that won’t deliver results.
#2: Magoosh: The Best Paid Option for Under $150
Magoosh provides a well-designed ACT course without a premium price tag. Starting at $129, their self-paced ACT prep course includes over 5,000 practice questions, up to 4 full-length practice tests, 250+ video lessons, and a 4-point score improvement guarantee, which is a rare feature to find at this price point.
Every practice question comes with a video or text explanation, so students aren’t left guessing why an answer was wrong. Questions are official, licensed ACT content, so practice closely mirrors what students will see on exam day. The Magoosh mobile app makes it easy to fit in study sessions anytime, anywhere.
Best for: Budget-conscious, lower-scoring students who still want a paid, structured course.
#3: Acely: The Biggest Question Bank
Acely is an AI-first, self-paced ACT prep platform with a large practice library and a study plan that adjusts based on your performance. Its annual plan costs $588 per year, or $49 per month billed annually, and includes 4,200+ ACT practice questions, 20 full-length ACT practice tests, an AI tutor for on-demand hints and explanations, score predictions, and progress reports that track accuracy, pacing, and weak areas. Acely also offers a three-day free trial.
Acely’s biggest strength is its large ACT practice library: the platform includes 5,000 practice questions and 20 full-length practice tests, giving students plenty of material for repeated timed practice. It also uses an adaptive study plan and AI-powered explanations to direct students toward weaker areas, and it advertises a 5-point score-improvement guarantee for students who meet its eligibility requirements.
Best for: Self-directed students who want a large ACT question bank, frequent full-length practice tests, and AI-generated study recommendations.
#4: Princeton Review ACT 31+: The Best Live Classes (With a Caveat)
Princeton Review’s ACT 31+ Course is built for students already scoring well who also want intensive live instruction to push into the 31+ score range. The course includes 36 hours of live classroom instruction, 5 full-length practice tests, and 8 single-section tests. You’ll also get Princeton Review’s score guarantee, which promises your money back if you don’t score a 31+ or gain 5 points from your starting score.
36 hours of live instruction beats most live-class competitors. The curriculum focuses on test-specific strategy instead of retreading content, which can be a great approach for students who already have a strong academic foundation but need to develop a test-taking strategy. The course includes printed materials and detailed score analyses after every practice test, giving families a concrete way to track progress as they seek a 31+ score.
Best for: Students already scoring in the high-20s who want a live, strategy-focused course and can commit to full attendance.
#5: C2 Education: The Best In-Person ACT Prep Option
C2 Education runs in-person learning centers across the U.S., plus an online option, with small group instruction from top-performing educators at a 3:1 student-to-teacher ratio. Every student starts with a free consultation and diagnostic test, then receives a personalized plan around their specific ACT weaknesses. Centers offer flexible evening and weekend scheduling.
For families who want face-to-face instruction in a physical classroom, C2’s small group ratios and local centers set it apart from other options on our list. The consultation-first approach means the study plan is tailored to the student’s needs, rather than a one-size-fits-all curriculum.
Best for: Families who prioritize in-person ACT instruction and are willing to do some legwork, including checking reviews for their specific local center before enrolling.
4 More ACT Prep Courses Worth Knowing About
While the following ACT prep programs didn’t make our top 5 due to pricing and fewer format options, it’s a good idea to have them on your radar as you compare your options.
PrepMaven
Boutique 1-on-1 tutoring with hand-selected tutors (many current Princeton undergrads), priced roughly $85-$200+ per hour depending on tutor tier.
Unlike its SAT offering, PrepMaven doesn’t provide a live group ACT class. Tutoring is the only offering for ACT prep, with no self-paced course or adaptive practice platform available. There’s no published score guarantee, and because pricing is hourly with custom quotes, it’s difficult for families to know their total cost upfront.
UWorld
A question bank of roughly 2,500-3,200 practice questions sold in 30-, 90-, 180-, or 360-day access windows rather than a single flat price, alongside a separate Complete ACT Prep Course still being rebuilt in 2026.
UWorld offers no live instruction and no adaptive study path. Students largely direct their own practice rather than following a plan that adjusts itself. At a comparable price point, PrepScholar and Magoosh both offer more structured, self-directing courses. There’s also no published score guarantee.
PrepExpert
Live 6-week cohort courses built around founder Shaan Patel’s strategy system, with self-paced and in-person options also available; the flagship live course typically starts around $999.
That’s noticeably pricier than comparable self-paced options. Magoosh’s course costs $129, and PrepScholar’s costs $397. PrepExpert’s 4-point guarantee also comes with strict attendance requirements, and missing multiple sessions in the compressed 6-week format can void eligibility entirely.
Kaplan (Self-Paced)
Kaplan’s entry-level Self-Paced course, built on an official partnership with ACT, Inc., typically runs $120-$180 and includes 30+ lessons, 2,000+ official practice questions, and several full-length official practice tests.
Unlike PrepScholar, Magoosh, and Princeton Review’s self-paced offerings, Kaplan’s entry tier includes no adaptive or personalized study path. That level of customization is reserved for Kaplan’s pricier live and tutoring tiers. There’s also no score improvement guarantee at the self-paced price point, unlike other companies on our list.
