Cheetah Prep FAQs

What is Cheetah Prep and how much does it cost?

+

Cheetah Prep is an online digital SAT prep platform that brings guided SAT lessons, 15,000+ practice questions, full-length mock exams, and adaptive score analytics together in one place. Premium access is $99/month and you can cancel anytime. Your subscription unlocks personalized SAT coaching, Desmos-powered math walkthroughs, and the complete digital SAT study experience for students working to raise their SAT score.

How is Cheetah Prep different from Khan Academy and other SAT prep courses?

+

Cheetah Prep uses learning science and adaptive algorithms to personalize your SAT prep in real time. Our 15,000+ human-vetted SAT practice questions are organized by skill, topic, and difficulty to match the digital SAT format. Unlike Khan Academy, our system focuses on your weak areas, combines SAT lessons with practice, and includes progress tracking and gamification to keep you motivated throughout your SAT study journey.

Can Cheetah Prep help me raise my SAT score?

+

Cheetah Prep is built to raise your SAT score by targeting your specific weak areas instead of having you re-drill what you already know. The platform combines lessons, adaptive practice, full-length digital SAT mock exams, and detailed analytics so you spend your study time where it moves your score the most. Consistent, focused practice with realistic SAT questions is the most reliable way to improve your SAT score.

How many SAT practice questions does Cheetah Prep include?

+

Cheetah Prep includes over 15,000 human-vetted SAT practice questions across every digital SAT section. Our question bank is aligned with College Board standards and the official digital SAT format, and it's organized by skill, topic, and difficulty so you can drill a specific weak area or take full-length SAT practice tests as you build toward your target score.

Does Cheetah Prep match the official Bluebook digital SAT format?

+

Yes. Cheetah Prep's questions, full-length mock exams, and tools are aligned with the College Board's digital SAT and the Bluebook testing experience, including the section-adaptive format and the embedded Desmos graphing calculator used on math questions. Practicing in a format that mirrors test day helps reduce surprises and build confidence before your official SAT.

How long should I study for the digital SAT?

+

Most students see the best results studying about 10 to 15 hours per week for two to three months, though your ideal SAT study plan depends on your target score and starting point. If your test is more than six months away, 8 to 10 hours per week is plenty, and in the final few weeks you should focus on full-length digital SAT practice tests and reviewing your mistakes. Cheetah Prep builds your study plan around your weak areas so every hour of SAT prep counts.

What is a good digital SAT score?

+

The digital SAT is scored from 400 to 1600, combining your Reading & Writing and Math section scores (200 to 800 each). A score above 1350 puts you in roughly the top 10% of test-takers, 1400+ is competitive for top-50 universities, and 1500+ is strong for the most selective schools, including the Ivy League. A good SAT score ultimately depends on the colleges you're targeting, and Cheetah Prep tracks your practice SAT scores so you always know how close you are to your goal.

How is the digital SAT different from the old paper SAT?

+

The digital SAT is taken on the College Board's Bluebook app and is section-adaptive: the difficulty of the second module in each section adjusts based on how you performed on the first. It's shorter — about 2 hours and 14 minutes — uses shorter reading passages, and lets you use a built-in Desmos graphing calculator on every math question. Cheetah Prep is designed specifically for this digital SAT format, including Desmos-based step-by-step walkthroughs.

Do I need prior SAT math knowledge before starting SAT prep?

+

No prior SAT knowledge is required. Cheetah Prep lessons cover all digital SAT topics from the ground up, including SAT math, reading, and writing. You can start at any level and work your way up. The platform is designed for students at every stage of SAT preparation, whether you're new to the SAT or preparing for a retake to improve your SAT score.

Can I track my SAT score progress and see improvement over time?

+

Yes. Cheetah Prep tracks your SAT performance across all sections, identifies your strengths and weaknesses by topic, and shows clear progress over time. You can view your SAT score trends, question accuracy by skill, and the areas that need more practice. This data-driven approach helps you focus your SAT study time where it matters most to maximize your SAT score improvement.

When should I start preparing for the SAT and when should I take it?

+

Most students take the SAT in the spring of junior year and again in the fall of senior year, which leaves time to retake it if needed. Starting your SAT prep two to four months before your test date gives you enough time to learn the content and complete several full-length practice tests. Because many colleges superscore — combining your best Math and Reading & Writing section scores across test dates — retaking the SAT can meaningfully raise the score colleges see.
