At Perfect800, we stand behind our service because we know it works. Unlike other Prep Companies who waste students' time with lectures, online videos, or "concept check" type questions that will never appear on your SAT, we give you the real deal - straight SAT Math questions with full explanations and tips.

Just like everything else in the world, practicing makes you better.

That's why we proudly guarantee results, with a money-back guarantee applying to anyone who uses our service and doesn't witness a score increase. Speaking of results though, nobody has ever asked for a refund.
