Summary: Best CLT prep resources (2025)
For students targeting religious colleges, select state universities, and, beginning in 2026, U.S. Service Academies, the Classic Learning Test (CLT) has emerged as a premier alternative to the SAT and ACT, offering an exam rooted in classical education principles. The CLT encourages students to sharpen their reasoning and critical thinking skills by analyzing impactful texts from throughout history. After a thorough review of the top CLT preparation courses, we've determined that Achievable delivers the most effective test prep solution for the CLT. This course offers personalized, results-driven strategies tailored to each student's strengths and areas for growth. Students seeking an all-in-one online test prep experience will appreciate Achievable's adaptive platform, packed with resources specifically designed to help candidates master every section of the CLT.
Achievable's course seamlessly integrates the CLT's emphasis on classical texts and rhetorical strategies with a state-of-the-art digital learning experience, setting a new standard for test prep. Introduced in 2015, the CLT is a unique exam that assesses students' reasoning, critical thinking, and reading comprehension by centering its passages on philosophical works, influential literature, and historical documents. Unlike the SAT and ACT, which focus more on contemporary education, the CLT is grounded in the Western canon, featuring excerpts from renowned thinkers such as Aristotle, Shakespeare, and Thomas Jefferson. The exam consists of Verbal Reasoning, Grammar/Writing, and Math sections (plus an optional essay), each requiring examinees to move beyond rote memorization by applying higher-level reasoning mastered through rigorous study. Due to the challenging nature of CLT content, structured preparation is necessary for students aiming to achieve top percentile scores. While some of the best preparation comes from cultivating a well-rounded reading list, prep courses allow students to take the time to practice and master the test format itself.
With the CLT being relatively new in the standardized testing landscape, students may wonder where they can find the most reliable test prep resources. Selecting the best prep solution can seem daunting, so we have compiled a list comparing highly rated providers, including Peterson's Test Prep, Mometrix, and Classic Test Prep. Our comparison features trusted names you can measure against our top choice for CLT preparation, Achievable. Each prep provider offers distinct benefits tailored to different learning preferences, from robust self-study tools to personalized tutoring support. We highlight key features of each CLT study program and share authentic student reviews to support your decision-making process. For maximum results, supplement your study plan with official CLT practice materials to gauge progress alongside third-party CLT resources. Ultimately, a flexible, guided course like Achievable's comprehensive CLT preparation delivers a clear structure for your study routine, featuring in-depth content reviews, proven techniques for mastering the test, and personalized score improvement plans to help you reach your full potential.

The program is further enhanced with instructional videos, interactive lessons, and detailed answer explanations, providing essential test-taking strategies and familiarizing students with the timing, question formats, and structure they'll encounter on the actual CLT exam.
For those seeking more than just self-paced study, Peterson's features a subscription-based model that unlocks access to dedicated CLT prep resources and an extensive range of other test-prep materials and courses.

For students who want a printed study book: Mometrix CLT
- Mometrix, a company known for its iconic yellow study booklets for professional certification tests, offers a workbook as well as a full online course for the CLT.
- Their dynamic online platform of study tools, offered through Mometrix University, is a great complement to their printed guide, which can also be purchased separately.

- Over 750 CLT practice questions, one of the largest question banks for the exam
- Money-back guarantee if you're not satisfied with their course after a week
- Heavy emphasis on proven spaced repetition techniques

- The textbook does not automatically come with the course
- The textbook list price is higher than the course subscription (for one month)
- 250+ review videos (over 20 hours of content)
- 70+ study lessons
- 340+ flashcards
- Post-lesson quizzes
- Progress tracking
- Bonus tools and tips
Mometrix delivers one of the most comprehensive CLT prep programs available, providing everything students need to succeed on the CLT exam. Their all-inclusive online course features over 70 detailed lessons, more than 340 targeted flashcards, 750+ CLT practice questions, and over 250 instructional videos.

In addition to their online prep course, Mometrix also provides a standalone CLT study guide, titled "CLT Secrets Study Guide." This easy-to-follow resource is organized in a step-by-step format with dedicated review sections for vocabulary, reading comprehension, grammar, math reasoning, and writing, all aligned with the structure of the official CLT exam. The study guide includes high-quality practice questions with thorough answer explanations, video tutorials, and essential test-taking tips. Mometrix is the ideal option for students seeking a flexible, self-paced approach to CLT study or for targeted review outside of a full course. While the study guide is all-inclusive, its list price of almost $60 is comparable to nearly two months of the online course, although it's likely Mometrix's strongest offering in its catalog. Mometrix is also known to be incredibly content-heavy, which may make their prep course more overwhelming than strategic for some learners.
“The company does an awesome job with educating and preparing students for learning concepts for tests and college. The material is well put together.”
“I like it, the resources are great, but the eBook is complicated to use when it comes to taking notes and finding pages. Also, when you purchase the eBook, you're sent a website link. You can not download or save the ebook you purchased to your files.”
Bottom line: Mometrix's CLT study guide is a high-quality resource from a well-known name in test preparation, though it's expensive for a prep book. Students can also explore the online course as an alternative CLT prep option, but some learners reported issues with Mometrix's digital resources.
Solid crash course: Classic Test Prep
- Classic Test Prep offers a 2-hour crash course for the CLT, which can be useful for examinees just getting started on their prep or to cap off a longer review period.

- A 2-hour "cram" course created for speedy reviews on key topics
- Comes with at least 2 full-length practice exams
- Tutoring and supplemental instruction can be added for around $200
- Not enough to be a comprehensive study resource on its own
- The tutoring package is more expensive than other prep options
- Video and text lessons
- Hundreds of practice questions
- Promises to improve test scores by 7 points
Classic Test Prep offers a structured online preparation program tailored specifically for the CLT exam, positioning itself as an effective supplement to more in-depth instruction for students focused on a classical education approach. With Classic Test Prep, students benefit from engaging video and text lessons, expertly crafted practice questions, full-length CLT practice exams, and test-taking strategies that accurately reflect the format of the real exam. These resources help users build familiarity with classical content while mirroring the rigorous digital environment found on some rival platforms.
Classic Test Prep prioritizes flexibility, offering multiple support tiers to accommodate various study goals and budgets. The "Crash Course" ($49) provides a focused 2-hour CLT review, including two full practice exams, ideal for last-minute preparation. For a more in-depth study, the "Online Course + Group Tutoring" package (approximately $240) combines instructor-led sessions with a set of structured online lessons, emulating the structure offered by leading competitors. For those seeking a fully personalized experience, one-on-one tutoring (about $587) includes weekly sessions and a custom study plan tailored to each student's unique needs. While this course is geared toward quick reviews, it's no replacement for the intensive drilling and practice needed to truly excel on an exam like the CLT. However, for students nearing the end of their study plan who want a quick overview of key topics, the crash course is a solid add-on. Be aware that, because Classic Test Prep is a relatively new test prep vendor, online reviews and feedback on their products are limited.
“Learning the strategies was super helpful, but also easy to understand. You really learn how to think about the question the right way.”
“The videos for the quantitative reasoning section helped so much!”
Bottom line: Classic Test Prep's Crash Course is a great last-minute study resource for visual learners and those looking for extra practice. Use it to enhance, not replace, your CLT study plan.
