Kaplan vs Princeton Review ACT: Direct Answer

Both Kaplan and Princeton Review provide high-quality ACT prep courses, but Princeton Review includes score guarantees and more live instruction options, making it ideal for students who value interactive learning and performance assurance.

Why This Matters

Choosing the right ACT prep course can significantly impact your test performance. With college admissions becoming increasingly competitive, a tailored prep course can serve as a critical tool for improving your ACT score, which might just be the differentiator in your application. Kaplan and Princeton Review are leading providers, and understanding their unique offerings can help you make an informed decision.

Curriculum Differences

Kaplan's curriculum emphasizes flexibility with its on-demand modules, allowing students to pace their learning. The recorded lessons cover all ACT sections and include practice tests that mirror the exam format. In contrast, The Princeton Review’s ACT 31+ Course offers structured live classes over several weeks with dedicated instructors, ideal for students seeking a classroom-like experience and motivational guidance.

Support and Resources

Both companies provide comprehensive support, but the format varies. Kaplan offers email and chat support embedded within their online platform, which is well-suited for self-driven students. You can also benefit from their mobile-friendly resources, making study convenient and accessible. The Princeton Review’s ACT Essentials Course includes interactive tools and direct access to instructors during live sessions for real-time feedback, a significant advantage if you prefer direct interaction with educators.

Score Guarantee

A major feature of The Princeton Review is its score improvement guarantee, applicable to their higher-tier offerings like the ACT 31+ Course, which ensures a refund or free course for students not achieving a score increase, as long as specific conditions are met. Kaplan does not feature a similar guarantee, an important consideration if assurance of score growth influences your decision.

Pricing Comparison

Kaplan’s ACT Prep program is priced at $499 as of May 2026, offering a blend of self-paced and pre-recorded session options. Meanwhile, Princeton Review course prices span from $199 for their Essentials Course to $899 for more intensive options like the ACT 31+ Course. Price differences reflect the level of live instruction and resources each option provides.

Delivery Format

Kaplan ACT Prep is primarily digital and self-paced, catering to students who appreciate flexibility in their study schedule. This approach is augmented by accessible online interfaces. Conversely, The Princeton Review excels in live classes, such as their multi-week and 31+ Course options, which are optimal for those who thrive in structured, interactive environments that mimic a traditional classroom setting.

How to Choose

• Choose Kaplan if you prefer digital learning flexibility and have a disciplined personal study regimen.
• Choose Princeton Review if you value live instruction, need motivational support from instructors, and want a score improvement guarantee that backs your investment.
