Yes, all our tests are official past exams from the latest Digital SAT examinations. This is unlike other websites that use mock tests or old SAT exams (often called SAT QAS) - which are no longer used by College Board.
College Board recycles a significant part of past papers to create new exams. You will likely encounter a number of past questions on your exam day. Past papers are the closest to the real exam, helping you prepare most effectively.
