To help you get a handle on what ACT prep entails, we’ll walk you through the core offerings of PrepScholar’s and Princeton Review’s ACT prep programs. You’ll have all of the information you need to decide which program is right for you!

PrepScholar ACT Prep Overview

PrepScholar provides four digital ACT prep options that are designed to meet every kind of learning need: Complete Online ACT Prep, Complete Online ACT Prep + Admissions Bootcamp, Live Instructor Led Classes, and 1-on-1 Online Tutoring.

PrepScholar’s most popular course, Complete Online ACT Prep, is a self-paced adaptive program that includes a smart diagnostic test, more than 50 skill lessons, 2800+ practice questions with explanations, and four official ACT exams to take as practice. This program comes with a year of full access to all included prep materials.

There’s also Complete Online ACT Prep + Admissions Bootcamp, which comes with everything that’s included in the Complete Online package, with the addition of Admissions Bootcamp lessons that take you through every step of the admissions process, from curating your college list, making your application stand out, how to write the perfect essay, how and when to submit your applications, and even financial aid.

PrepScholar’s Live Instructor Led Classes give you up to 36 hours of expert-led classes in a live, online classroom. You’ll get to learn in a small group of up to nine other students and get feedback and answers to your questions in real-time. This program includes everything in the Complete Online ACT Prep program as well as the Admissions Bootcamp, both at no additional cost.

With the 1-on-1 Tutoring program, you can get 4, 10, 18, or 32 one-on-one tutoring hours with a 99th percentile-scoring tutor. You’ll pick the tutoring package that best fits your schedule, needs, and goals, and receive a fully personalized prep experience.

Each of PrepScholar’s ACT prep programs include a 4-point guarantee, customized weekly prep plans, and 60+ hours of prep content.

UWorld ACT Prep Overview

UWorld’s suite of ACT prep programs include three main offerings: Complete ACT Prep course, ACT QBank, and ACT Study Guide.

The Complete ACT Prep Course is a self-paced, asynchronous course that students move through independently. With this package, you’ll get instructional videos, a print and digital study guide, practice materials including 2,500+ practice ACT questions and smart flashcards, a timed test simulation, and a progress dashboard to track your performance. This course is currently being rebuilt by UWorld and, because of this, some information is missing online, like the access period for course subscriptions and program costs.

Then there’s the ACT QBank, a package that includes access to UWorld’s full repository of practice ACT questions, flashcards, a customizable quiz generator, timed test simulation, and progress dashboard. QBank subscriptions come in 30 day, 90 day, 180 day, and 360 day access packages.

UWorld also offers an ACT Study Guide package. Like the ACT Prep Course, this package is currently under construction, so pricing and access periods for subscriptions aren’t currently listed online. UWorld does state that Study Guide packages will include a digital and print ACT Math and ACT English & Reading book, which contain study guides, lessons, and practice questions that are unique to the prep books.

UWorld does not provide any live instruction courses, one-on-one tutoring packages, or a score guarantee.

PrepScholar vs. UWorld Comparison Table

To help you get a sense of how they compare to each other, here’s a side-by-side breakdown of each ACT prep option that PrepScholar and UWorld offer.

Comparison Point 1 – Instruction Quality and Feedback

A quality ACT prep program provides instruction and feedback that meets students’ learning needs and helps them achieve their goals. Here’s how PrepScholar and UWorld compare on instruction quality and feedback.

PrepScholar

All of PrepScholar’s ACT programs are built on the idea that customized, strategic practice is key to mastering the exam. Their curriculum focuses on helping students understand how the ACT works and teaching them to outsmart its tricks, which are both essential to meaningful score improvement.

Every program includes 60+ hours of instructional content and 50+ skill lessons covering the ACT’s most critical content areas. Lessons blend video and text instruction into short, digestible chunks, followed by quizzes that reinforce learning and flag gaps for future practice.

Where PrepScholar really shines is in how they handle wrong answers. All 2,800+ practice questions come with detailed explanations that break down why each incorrect answer is wrong, how it was designed to mislead you, and how to approach similar questions going forward, which is crucial to translating practice into real score gains.

PrepScholar’s four included practice tests are sourced directly from the Official ACT Prep Guide, reflecting their belief that official materials are the most effective prep available. After each test, students receive targeted feedback to help them track their progress and stay focused on their weakest areas.

For students who want more hands-on guidance, PrepScholar’s one-on-one tutoring pairs them with experienced, 99th-percentile scoring ACT tutors. Tutors are trained to build individualized strategies, run customized sessions, and zero in on each student’s weak spots to eliminate mistakes and drive score improvement.

UWorld

UWorld provides what have been described as visually engaging, dynamic asynchronous video lessons, taught by real teachers with years of experience. However, UWorld does not provide any live instruction courses or one-on-one tutoring options, which may limit the range of learning needs that they can serve.

In both their Complete ACT Prep course and their ACT Study Guide, UWorld places a strong emphasis on making learning materials clear, concise, and visually appealing, using full-color in their prep books rather than the typical black-and-white. Guided by their three-step watch, read, and practice method, UWorld’s ACT prep materials provide easy-to-understand guidance for students who are willing to learn independently.

One area where UWorld’s ACT prep gets a lot of praise is their detailed answer explanations. These explanations are provided for every answer in the QBank. They teach the “why” behind every correct and incorrect answer so students can learn from their mistakes in real-time.

UWorld’s bread and butter is self-guided prep. This means that they don’t provide any prep options that include live instruction courses or one-on-one tutoring. UWorld is designed for students who want to prep on their own, without additional guidance from instructors or tutors.

Winner: PrepScholar

UWorld’s self-guided ACT prep is a great fit for students who feel confident in handling their ACT prep all on their own. But PrepScholar’s foundational self-paced ACT prep can be combined with live instruction and one-on-one tutoring options that UWorld doesn’t have.

With PrepScholar, students have the advantage of customizable self-paced prep and face-to-face guidance from 99th percentile-scoring ACT prep experts. Because of their range of high-quality ACT instruction formats, PrepScholar is the clear winner when it comes to instruction quality and feedback.

Comparison Point 2 — Personalization and Adaptive Learning

Effective test prep continuously adapts to your performance and personalizes your study plan so you can stay focused on your unique goals. Read on to find out how UWorld and PrepScholar compare on this crucial aspect of ACT prep.

PrepScholar

Personalization and adaptiveness are at the core of PrepScholar’s ACT prep philosophy. Their programs use a skill-by-skill approach to learning that adapts to each student individually, allowing them to focus on areas where they need the most improvement.

When students sign up, they complete an initial smart diagnostic assessment that evaluates their performance across every skill that pops up on the ACT. PrepScholar then uses the results from the diagnostic to generate a fully personalized weekly study plan that’s tailored to the skills, content, and practice a student needs based on their current performance. The study plan is adapted week by week to ensure that students are focusing on the areas where they need the most improvement, which is the best use of your prep time.

PrepScholar’s adaptive technology adjusts to the student’s performance with each question, which allows you to make more progress in less time. As you complete quizzes and practice tests, your weekly study plan continually updates to keep you focused on the skills and content that will help you progress quickly.

Students who enroll in PrepScholar’s one-on-one tutoring receive an additional layer of personalization. Using diagnostic data from students’ ongoing performance on drills and practice exams, PrepScholar connects students with a tutor who’s an expert in their weak areas. Tutors build each session around the student’s progress and adjust the study plan to provide targeted practice from one week to the next.

UWorld

UWorld has built some adaptivity into its self-guided ACT prep course through diagnostic testing and tools that students can use to customize their study plan.

When students begin the UWorld ACT course, they take a self-assessment that’s used as a baseline diagnostic tool to help you identify weak areas to focus on. From there, students can use the progress tracking platform to keep track of their weaknesses, and create custom quizzes that target those areas. Through this approach, students can focus on improving their weaker areas, which is the best way to improve their scores.

While UWorld’s self-guided course provides plenty of opportunities for students to customize their own prep, this company doesn't offer any live instruction or one-on-one tutoring options. Many students who have completed an ACT prep program claim that the personalization that comes with live, one-on-one guidance is the thing that moved the needle for them. Students who are seeking more personalization options will need to seek out a different ACT prep program to meet those needs.

Winner: PrepScholar

Both UWorld and PrepScholar’s self-guided courses are adaptive. But PrepScholar’s entire suite of ACT prep includes a built-in program that adapts to your progress lesson by lesson, recalibrating in order to meet the unique learning needs and goals of each student. Combined with live instruction and one-on-one tutoring, PrepScholar’s purpose-built adaptivity algorithm makes them the undeniable winner.

Comparison Point 3 — Test Updates and Alignment

In order for an ACT prep program to be effective, it has to be fully aligned with the most current version of the ACT. Here’s how UWorld and PrepScholar stack up when it comes to test updates and alignment.

PrepScholar

PrepScholar’s ACT Prep has been fully redesigned to reflect the new Enhanced ACT that came out in 2026. While many other test prep companies have simply tweaked their programs, PrepScholar has rebuilt their ACT prep from the ground up, redesigning lessons, practice questions, and their entire interface to give students the most realistic experience possible.

This ACT prep program update comes with 50 refreshed skill lessons that align with the skills tested on the Enhanced ACT, new strategy lessons that target the structure and tricks of the ACT, expanded coverage of skills that weren’t emphasized in English, Math, and Reading on the old ACT. You’ll also have the option to opt out of Science prep if you don’t plan to take that optional section of the ACT.

Additionally, the updated ACT prep program includes 2800+ brand new practice questions, Math questions that have been fully rewritten for the ACT’s new four answer choice format, and a refresh to the prep interface that aligns it more closely with the ACT’s new section lengths and pacing.

PrepScholar recognizes that the ACT is still in transition. That’s why their redesigned ACT prep program continues to cover both paper-and-pencil and digital exam delivery formats.

Thanks to these updates, PrepScholar is able to provide a fully emulated Enhanced ACT prep experience, with an interface that’s designed to mirror the ACT’s new format and design, so students can get an authentic feel for what it’ll be like on exam day.

UWorld

UWorld is currently in the process of reworking their ACT prep course and study guide packages to make them fully aligned with the Enhanced ACT. Because of this, their ACT Prep Course and Study Guide packages are currently unavailable, but you can sign up to be notified via email when the new prep materials go live.

In addition to making changes when the ACT undergoes a major transition, UWorld’s content team continuously reviews test trends to make sure their video lessons, books, and ACT QBank questions match what you’ll actually see on exam day. Right now, it isn’t clear what UWorld’s updated ACT prep material

s will look like or how much they will cost. While you’re waiting to find out, you can take advantage of a 7-day free trial to get a feel for UWorld’s approach to ACT prep.

Winner: PrepScholar

UWorld explicitly states that their ACT prep program is continuously updated to align with the real ACT. But when the new Enhanced ACT came out, PrepScholar rebuilt their entire ACT prep program from the ground up to provide the most realistic prep experience possible–and that’s what makes them the clear winner when it comes to test updates and alignment.

Comparison Point 4 — Value

The value of an ACT prep program depends entirely on how well it meets your learning needs and helps you achieve your goals. Below, we cover how PrepScholar and UWorld compare in terms of the value their ACT prep programs provide.

PrepScholar

PrepScholar offers four ACT prep programs: Complete Online ACT Prep, Complete Online + Admissions Bootcamp, Live Instructor-Led Classes, and One-on-One Tutoring. Higher-tier programs add more personalization and cost more accordingly.

The flagship self-paced option, Complete Online ACT Prep, includes a smart diagnostic test, 2,800+ practice questions, drills, lessons, four practice exams, and detailed answer explanations. The program continuously adapts your study plan based on performance, though it doesn’t include any live or one-on-one instruction.

Every higher-tier program builds on Complete Online’s foundation, layering additional personalization on top of its built-in adaptivity. All upper-tier plans include PrepScholar’s Admissions Bootcamp at no extra cost, and bundling SAT prep with ACT prep is straightforward. Live Instruction packages range from 4 to 32+ hours across Beginner, Essentials and Advanced tracks, while One-on-One Tutoring is available in 4, 10, 18, or 32-hour packages.

All programs come with a 4-point score improvement guarantee for students who meet course requirements. A few reviews have flagged challenges with the refund process, so reading the guarantee terms carefully before seeking a refund is a must. It’s also worth noting that while PrepScholar is accessible on mobile, there’s no dedicated app, so expect a different experience if you choose to study on your phone.

Across every tier, PrepScholar’s adaptive technology delivers a meaningfully personalized experience. When a program is tailored to your specific needs and goals, you’re getting maximum value for every dollar spent.

UWorld

UWorld offers three types of ACT prep: Full ACT Prep Course, ACT QBank and ACT Study Guide. However, some ACT prep materials are currently being updated to align with the new Enhanced ACT. Because of this, both the Prep course and Study Guide are not available for purchase at this time, and it isn’t clear when the new prep materials will be released.

If you would like to be notified when the new Prep Course and Study Guide become available, UWorld invites you to sign up for emails. In the meantime, UWorld’s ACT QBank offers 2,500+ practice questions that you can use to create custom quizzes and replicate the real exam format, but UWorld hasn’t stated whether these practice questions have been updated to align with the new ACT.

Because their ACT prep program is currently in limbo, it isn’t clear what kind of value students might take away from UWorld’s ACT prep. It may be worth it to wait and check back in after all of UWorld’s ACT prep has been fully updated. Some reviewers also suggest speaking with a UWorld representative if you want to get a better sense of what the new ACT prep packages will include.

All of UWorld’s ACT prep is completely self-paced, with no live instruction or one-on-one tutoring options available.

While it’s likely that UWorld’s new ACT prep programs will be comparable in cost to their SAT prep, because pricing isn’t currently published on their website, it isn’t possible to know for sure.

UWorld states that many students who fully engage with their ACT Prep Course often see 5-9 point improvements from their first and official ACT scores. It’s worth noting that this is not a formal score guarantee, and UWorld does not provide one for any of its ACT prep programs.

Winner: PrepScholar 

At present, it isn’t clear what UWorld’s ACT prep courses cost–or when they’ll be available for purchase. For students seeking a full year of affordable prep that can be combined with customizable one-on-one prep packages right away, PrepScholar is the winner.

Frequently Asked Questions (FAQs)

After reading through all this information about PrepScholar and UWorld ACT prep programs, you may have some additional questions. We’re covering the most frequently asked ones below.

 

Is PrepScholar or UWorld better for ACT prep?

While both programs provide quality, adaptive prep, they’re designed for students with different learning needs and goals. UWorld may be a good fit for students who are seeking strictly self-guided practice for a short period of time. For independent students seeking a program that continuously adapts to their needs and grows as they grow, PrepScholar is the top choice for ACT prep.

 

What is the best ACT prep program in 2026?

PrepScholar’s ACT Complete Online Prep provides adaptive, personalized ACT prep, administered by 99th percentile-scoring tutors. It’s focused on helping students identify and drill the areas that are most likely to improve their score, adapting to their progress to continuously pinpoint students’ strengths and weaknesses. With more than 50 skill lessons, over 2,800 practice questions, and four official ACT practice tests, ACT Complete Online Prep is the program that’s most likely to bring you real, measurable results over time.

 

How often should test prep materials be updated for them to be reliable? 

A sign of a trustworthy, reliable test prep program is its responsiveness. When the SAT, ACT, or any other standardized test changes, test prep programs should be proactive about updating their materials to mirror the latest exam version as authentically as possible. If a test prep company responds proactively to exam changes, uses expert-backed learning theories to shape their prep program, and leverages new technology to improve test prep, it’s a good sign that their prep materials are reliable.

 

How important are test score guarantees? 

Score guarantees can be a meaningful sign of confidence in a test prep program’s effectiveness, but they shouldn’t be the defining factor in your prep program selection. Many test prep guarantees come with strict requirements and confusing fine-print. What matters most in the long run is that the program you choose provides a high-quality, engaging prep experience that empowers you to meet your goals.
