Absolutely. Every question and passage in our PrepPack™ has been specifically designed to match the new Digital SAT format. We focus on the shorter reading passages and the updated math domains, ensuring you are practicing the exact material you will see on test day.
While the free product recommended by the College Board offers foundational practice, our PrepPack™ provides high-intensity simulations developed by Isaac, our standardized test expert with over 30 years of experience. We provide more rigorous "Hard" level questions and detailed, step-by-step explanations that teach the logic behind the test, not just the correct answer.
Our current tests are Linear (Fixed-Difficulty). We chose this format to ensure you get exposure to the full range of questions—from easy to very challenging—in every single practice session. Unlike adaptive tests that might "hide" harder questions if you make a small mistake early on, our linear tests guarantee you get the practice you need on every single topic to build maximum stamina for the real exam.
Yes! Our platform is fully optimized for desktops, laptops, and all mobile devices. Since the real DSAT is taken on a specific, registered device, we recommend practicing on the same hardware you plan to use on test day to get comfortable with digital navigation and on-screen reading.
Isaac is a veteran of psychometric test development with three decades of experience. He has analyzed thousands of real test items to create "clones" that mirror the College Board’s specific traps and patterns. When you study with our pack, you are studying the most authentic material available outside of the official Bluebook app.
You will have full, unlimited access to all tests and guides for the duration of your license. This allows you to revisit difficult topics and retake sections as many times as necessary to achieve mastery.
Our "Practice History" feature allows you to see exactly where you are losing points. Every incorrect answer includes a comprehensive explanation. By reviewing these, you can turn your weaknesses into strengths before you step into the testing center.
