FAQ
Questions before you start.
Still unsure? Email us at yoonshiky@g.ucla.edu — we reply within 24 hours.
Is DSAT affiliated with College Board?
No. DSAT is an independent practice platform. College Board® and Bluebook® are registered trademarks of College Board. We are not affiliated with, endorsed by, or connected to College Board in any way.
Are these real SAT questions?
Official SAT questions are copyrighted and cannot be used by any third party. Our questions are hand-written by our team to match real Digital SAT difficulty and format — the same approach every legitimate prep company takes. None are AI-generated.
How is this different from official Bluebook tests?
Bluebook offers a limited number of official tests with no score explanations. We offer 10+ full-length mocks, per-question explanations, a detailed score breakdown, and an enforced 10-minute break in Scored mode — a closer simulation of actual test day.
Does this prepare me for test day?
College Board research shows students who complete 3+ full-length mocks gain an average of 60 points over those who don't practice at all. Our platform is built around stamina and stage-adaptive logic — the two things most students are underprepared for.
What happens after I finish a test?
You get an instant 400–1600 score with separate Reading & Writing and Math subscores. You can then review every single question with full explanations — seeing exactly where you lost points and why. Answers, highlights, and notes are all saved so you can return anytime.
Can schools or academies use DSAT?
Yes. Schools and academies can purchase tests for student cohorts without subscriptions or contracts. If you're an educator or academy director, email yoonshiky@g.ucla.edu to discuss setup.
What is your refund policy?
Full refund within 7 days of purchase if the test has not been accessed. Once accessed, refunds are not available due to the nature of digital content. Technical errors preventing access are handled case by case — email yoonshiky@g.ucla.edu or call 02-6959-4599.
