When I reviewed the best ACT prep courses, I focused on one thing that actually raises scores: taking practice tests and testing strategies. A landmark study published in Science found that students who used practice tests retained about 50% more information after one week than those who simply restudied.
With that in mind, I tested each ACT prep course hands-on, working through practice questions, reviewing explanations, and comparing how closely the material matched the real ACT. I paid special attention to ACT math, the science section, pacing, and whether the tools truly help improve ACT scores.
Here is what I found: a side-by-side comparison, followed by a deeper breakdown of each course.
Which ACT Prep Course Is Right for You?
- Pick UWorld if… you want the most realistic ACT practice and learn best by drilling high-quality questions with clear, visual explanations.
- Choose PrepScholar if… you want a structured weekly study plan and official ACT tests that tell you exactly what to work on next.
- Go with Achievable if… you prefer reading over videos and want an efficient, self-paced program without extra fluff.
- Pick Prep Expert if… you need live classes, accountability, and strong test-taking strategies taught by an instructor.
- Choose Kaplan if… you want a traditional ACT prep experience with official questions and optional tutoring.
- Go with Magoosh if… you want affordable, flexible ACT prep with video explanations that fit a busy schedule.

How I Approached This Review to Rank the Best ACT Courses
As a reviewer, I focused on what actually moves the needle for test takers:
- How realistic did the ACT practice questions felt
- Whether explanations helped me change how I approached questions
- Tools that reduce test anxiety by improving familiarity
- Flexibility for students studying at their own pace
- Support for different learning styles
I wasn’t trying to “pass” the ACT myself, but I evaluated each platform the way a motivated student would when aiming for a higher score.
1. UWorld: Best ACT Prep Course Overall
My Experience
UWorld stood out immediately when I started testing it. The biggest difference I noticed was how realistic the practice felt. The ACT questions didn’t feel simplified or “test-prep-ish”; they felt like something I’d expect to see on the actual exam, especially in ACT math and the science section.
I also really liked the visual, step-by-step explanations. When I missed a question, I didn’t just see the correct answer. I could clearly see why each wrong answer failed. That’s huge for improving accuracy on a multiple-choice test like the ACT.

“I loved using UWorld to get reps in. They have a huge question bank. Really good if know what you need to work on and get content down.”
Reddit Review
Pros
- High-quality practice questions feel closest to the real ACT
- Excellent visual and written explanations
- Strong tools for pacing and test day strategy
- Flexible access lengths for different test dates
Cons
- No live classes or tutoring
- Best for students comfortable with self-paced learning
UWorld ACT Course Discount
Bottom Line
If I had to recommend one ACT prep course to most students aiming for their best ACT score, UWorld. The quality of practice alone puts it ahead of the pack.
UWorld ACT
2. PrepScholar: Best for Structured ACT Prep
My Experience
PrepScholar felt more structured than UWorld. When I tested it, the platform quickly pushed me into a customized weekly study plan after a diagnostic test. I liked how it kept redirecting me back to weaker areas instead of letting me avoid them.
The inclusion of official ACT practice tests is a big plus, and the optional Admissions Bootcamp adds value for families focused on the broader college application process.
Pros
- Strong structure and accountability
- Official ACT exams included
- Helpful for students who want a clear plan
Cons
- Practice questions felt slightly less realistic than UWorld’s
- Higher cost at advanced tiers
PrepScholar ACT Course Discount
Bottom Line
PrepScholar is a solid choice for students who want guidance, structure, and admissions support built into their ACT test prep.

3. Achievable: Best Self-Paced ACT Prep
My Experience
Achievable felt refreshingly simple in a way that was clearly intentional. As soon as I started using it, I liked the online textbook format and how efficiently I could move through material without sitting through long video lessons.
The platform is designed to help you learn quickly, and I found the explanations concise yet thorough enough to clarify mistakes and reinforce key concepts. It worked especially well for focused study sessions, where I wanted to read, practice, and move on without distractions or unnecessary features getting in the way.
This course felt best suited for disciplined students who prefer reading and efficiency over bells and whistles.
Pros
- Clean, distraction-free interface
- Adaptive learning without overcomplication
- Excellent value for the price
Cons
- No live online instruction or tutoring
- Less multimedia than other platforms
Achievable ACT Course Discount
Achievable Deal – Free Practice Exam On ACT Course
Bottom Line
Achievable is a great pick if you want a no-frills, self-paced ACT prep course that respects your time.

4. Prep Expert: Best Live ACT Prep Classes
My Experience
Prep Expert felt intense in a good way from the start. The emphasis on live instruction, accountability, and mindset stood out immediately, and the structure made it clear that the course is designed to keep students engaged and on track. That structure aligns closely with feedback I’ve seen from parents, including one mom who shared that her daughter took the ACT twice, once with Prep Expert and once without brushing up using test prep, and saw a noticeable drop in performance the second time.
“She was motivated and committed. Her score went from composite 22 to a superscore of 27 so do think it was worth it. The following ACT she only got a 23 composite (in the middle of lacrosse season and she didn’t brush up on anything before she took it) so this tells me all the practices tests and proximity of the classes to the test made a huge difference for her. She would say the same.”
Reddit Review
I also liked that the video lessons show the instructor actively working through questions with you, explaining not just the correct answers but the reasoning and strategies behind them. That guided, step-by-step approach made the material feel more interactive and helped reinforce how to think through questions under timed conditions.
Pros
- Live classes with top-percentile instructors
- Strong focus on strategy and pacing
- Industry-leading score guarantee
Cons
- Less flexible than self-paced options
- Higher cost commitment
Prep Expert ACT Course Discount
Bottom Line
Prep Expert is best for students who want live guidance, motivation, and accountability throughout their ACT prep.

5. Kaplan: Best Traditional ACT Prep Course
My Experience
Kaplan felt familiar and reliable from the moment I started using it. I liked having access to official ACT practice problems, which added credibility and realism to my prep sessions. The option to mix on-demand lessons with live instruction or tutoring also stood out, since it allows students to adjust their level of support as they go.
It’s not the most modern platform I tested, but it’s dependable and thorough.
Pros
- Official ACT materials
- Multiple formats (self-paced, live, tutoring)
- Trusted brand with a long track record
Cons
- Interface feels less modern
- Can get expensive with add-ons
Kaplan ACT Course Discount
Bottom Line
Kaplan is a strong choice if you want a traditional, classroom-style ACT prep experience.

6. Magoosh: Best Budget-Friendly ACT Prep
My Experience
Magoosh was easy to use and flexible from the moment I logged in. One of the first things I noticed was how clear and readable the dashboard was. Everything was laid out so it was easy to understand what to study next without feeling overwhelmed. I liked the video explanations, curated study schedules, and progress tracking, and the overall design felt especially approachable for students who are new to standardized tests.
“I have used Magoosh for test prep and really liked it. My favorite thing about Magoosh is that their video explanations are super clear, and the practice questions feel really similar to the real test.”
Reddit Review
The question bank is smaller than some top-tier options, but the value is solid, particularly for students who want a straightforward, user-friendly ACT prep experience.
Pros
- Affordable pricing
- Good explanations
- Flexible self-paced study
Cons
- Smaller question pool
- Less advanced analytics
Magoosh ACT Course Discount
Bottom Line
Magoosh is a good entry-level online ACT prep course, especially for budget-conscious families.

7. Acely: Best for AI-Driven Practice
My Experience
Acely focuses heavily on AI-generated practice and quick drill creation. I liked how quickly I could generate targeted question sets, and the platform makes it easier to schedule frequent full-length practice when paired with the limited number of official ACT tests available.
That said, while the volume of practice can help build familiarity and confidence over time, I found the explanations less detailed than those in top-tier prep courses, which may limit how much insight students gain from their mistakes.
Pros
- AI-powered practice generation
- Affordable option
Cons
- Explanations lack depth
- Limited live support
Bottom Line
Acely works best as a supplemental ACT practice tool, not a standalone prep solution.
Acely
8. C2 Education: Best In-Person ACT Prep
My Experience
C2 Education offers a very hands-on, tutor-driven ACT prep experience built around individualized study plans. The process begins with a full-length diagnostic test under real test conditions, which tutors then use to identify strengths and weaknesses and shape instruction. While this level of personalization can be helpful for some students, it also means the experience depends heavily on tutor quality, availability, and location.
Pros
- Personalized tutoring
- In-person and online options
Cons
- Expensive
- Less flexible scheduling
Bottom Line
C2 Education is best for families seeking high-touch, tutor-led ACT prep.

9. The Princeton Review: Best for Brand Recognition
My Experience
The Princeton Review offers comprehensive materials and live instruction, but I found the experience less focused than some newer platforms. That made the program better suited for targeted concept reinforcement rather than fast, step-by-step practice designed to mirror exam conditions.
“Honestly, the most important thing to know about princeton review is that it’s really about how you use it, not just the material itself…their english section was solid for grammar rules, but their math explanations sometimes felt too wordy when i just needed to see the steps.”
Reddit Review
Pros
- Well-known brand
- Live classes available
Cons
- Can feel overwhelming
- Less adaptive learning
Bottom Line
The Princeton Review is a recognizable option, but not my top choice for modern ACT test prep.

10. IXL Learning: Best ACT Skill Reinforcement
My Experience
IXL felt more like skill practice than full ACT prep. I found it useful for reinforcing math questions and core fundamentals, especially early on, but it does not replace the need for realistic ACT practice tests. It works best as a starting point or a supplement, rather than as a complete ACT test-prep solution.
“It’s a good place to start, but nothing beats practice tests.”
Reddit Review
Pros
- Strong skill-building tools
- Helpful for ACT math reinforcement
Cons
- Not full ACT prep
- No realistic practice tests
Bottom Line
IXL works best as a supplement, not a standalone ACT prep course.
IXL Learning
Honorable Mentions:
These courses didn’t rank in my top tier, but they may still work for certain students or as supplemental resources.
Study.com: Study.com is useful for general subject review, but its ACT-specific practice is less realistic than the top prep courses. It works best as a supplement rather than a primary ACT prep option.
Peterson Test Prep: Peterson Test Prep offers traditional ACT materials and practice tests, but the platform feels less modern and less adaptive than higher-ranked courses.
Final Thoughts
After reviewing all of the ACT prep courses in this guide, it’s clear that there isn’t a one-size-fits-all solution. Some programs stand out for realistic practice, others for structure, live instruction, or affordability. What matters most is choosing a course that matches how you learn and how consistently you’ll actually use it before your test date.
The good news is that every course on this list serves a different type of student. Whether you prefer self-paced study, guided plans, or live instruction, the right ACT prep course can help you feel more confident, reduce test anxiety, and walk into test day better prepared.
