Kaplan OAT Review: Books, Question Bank, Practice Tests, and Value [2026]

Kaplan has been a household name in admissions test preparation for more than fifty years. While newer digital question banks have entered the market, Kaplan continues to attract pre-optometry students who prefer an established curriculum, physical printed books, and structured live instruction.

Kaplan offers several distinct options for the Optometry Admission Test (OAT). Students can purchase the standalone Kaplan OAT Prep Plus review book, enroll in a self-paced on-demand digital course, or attend scheduled Live Online webinar classes taught by expert instructors.

In this thorough 2026 review, we analyze Kaplan's curriculum, assess the realism of its 7 full-length practice tests, examine the 3,500+ question QBank, evaluate course pricing, and compare its value against OAT Booster, Chad's Prep, and OAT Destroyer.

Key Takeaways

• Course Formats: Available as a standalone paperback book, a self-paced on-demand video course, or scheduled live online classes.
• Practice Tests: Includes 7 full-length computer-based practice exams that simulate the timing and fatigue of the 4.5-hour official test.
• Review Books: The Kaplan OAT Prep Plus book provides clear chapter summaries, concept checks, and full-color scientific diagrams.
• Score Guarantee: Comprehensive course enrollments feature Kaplan's higher score guarantee, offering free course repeats or refunds for eligible retakers.
• Scoring Warning: Proprietary practice exam scoring curves can be deflated, often scoring students lower than their eventual official ADA results.
• Pricing: Standalone book ranges from $65 to $95; Self-Paced courses are $1,299 to $1,599; Live Online classes range from $1,699 to $2,099.

The Kaplan OAT Learning System

Kaplan structures its OAT preparation around three core components: content acquisition, targeted practice, and full-length exam simulation.

Unlike digital-only platforms that require all studying to take place in front of a computer monitor, Kaplan provides physical reading material through its comprehensive OAT review book. Each chapter covers a specific science or math domain, followed by practice quizzes to verify retention.

Students enrolled in digital programs access an online portal that pairs book chapters with video lessons, customized question sets, and diagnostic analytics tracking performance across all four test sections.

Detailed Feature Analysis

1. The Kaplan OAT Prep Plus Book

The foundation of Kaplan's curriculum is the Kaplan OAT Prep Plus book. Spanning hundreds of pages, this text covers:

• Biology: Cellular biology, genetics, human anatomy and organ systems, ecology, and evolutionary taxonomy.
• General Chemistry: Atomic structure, periodic trends, stoichiometry, thermochemistry, equilibrium, and electrochemistry.
• Organic Chemistry: Nomenclature, stereochemistry, substitution and elimination reactions, carbonyl chemistry, and spectroscopy.
• Physics: Kinematics, Newtonian dynamics, rotational physics, optics, refraction, wave phenomena, and electricity.
• Reading Comprehension & Quantitative Reasoning: Pacing frameworks, passage mapping, arithmetic, algebra, and geometry.

The book is structured with clear headings, bulleted lists, and Kaplan Method strategy callout boxes. It is easy to highlight and annotate, making it an effective tool for students who retain information better through tactile reading.

2. Live Online Interactive Classrooms

For pre-optometry students who struggle to stay on schedule with independent study, Kaplan's Live Online course provides an interactive classroom experience.

Classes meet weekly in multi-hour sessions led by an experienced instructor. Instructors review high-yield concepts, solve tricky optics problems on a digital whiteboard, and teach elimination strategies for multiple-choice questions.

Students interact through a live chat window, typing questions and receiving immediate feedback without interrupting the lecture. If you miss a scheduled class, complete video recordings are available on demand in your student portal.

3. 7 Full-Length Practice Exams

Taking full-length practice tests is necessary to build the mental endurance required for the 4.5-hour OAT. Kaplan includes 7 full-length computer-based practice exams.

These practice tests replicate the section order, question counts, and break times of the official exam:

1. Survey of the Natural Sciences: 100 questions (90 minutes)
2. Reading Comprehension: 50 questions (60 minutes)
3. Optional 30-minute break
4. Physics: 40 questions (50 minutes)
5. Quantitative Reasoning: 40 questions (45 minutes)

Taking multiple full-length exams helps you practice time management, particularly on the Physics section where students often run short on time.

4. Practice Exam Score Deflation

One important caveat regarding Kaplan practice exams is score deflation. Many students notice that their practice test scores on Kaplan are 15 to 30 points lower than their actual performance on official ADA diagnostic exams.

Kaplan practice tests often feature dense calculation steps and strict scoring scales. A student scoring 310 on a Kaplan practice exam might score 330 or 340 on the real exam. Keep this in mind during your preparation so you do not become discouraged by lower practice test numbers.

5. 3,500+ Question Bank (QBank)

Kaplan's digital QBank allows you to generate custom practice quizzes filtered by subject, topic, and difficulty. You can choose timed mode to practice pacing or tutor mode to see answer explanations immediately after submitting each question.

While Kaplan's question bank is thorough and covers all required content areas, its answer rationales are text-heavy and lack the extensive video solutions and visual diagrams found in OAT Booster.

Kaplan OAT Course Options and 2026 Pricing

Kaplan offers three main paths depending on your budget and preferred study format:

For students on a modest budget, purchasing the physical Kaplan OAT Prep Plus book ($65 to $95) and combining it with OAT Booster's question bank and Chad's Prep videos provides a comprehensive study setup for under $450.

Kaplan vs Competitors

Here is how Kaplan compares to alternative study platforms from our Best OAT Prep Courses guide:

• Vs OAT Booster: OAT Booster offers more practice questions (8,800+ vs 3,500+), an authentic Prometric testing interface, and detailed biology cheat sheets for $299. Kaplan is more expensive ($1,299 to $1,699+), but provides live interactive classroom sessions and a comprehensive physical textbook.
• Vs Chad's Prep: Chad's Prep offers superior conceptual video instruction for general chemistry, organic chemistry, and physics at an affordable monthly rate. Kaplan's video lessons are more formal and less engaging than Chad's whiteboard explanations.
• Vs OAT Destroyer: OAT Destroyer is a physical workbook focused purely on high-difficulty science drills. Kaplan provides a broader testing ecosystem with computer-based practice tests, full-length simulations, and live teacher support.
