Is Rivie free?
Yes. The free plan has no time limit and needs no credit card. It includes a full-length practice test with its score report and 100 practice questions a week. Pro opens everything else, from $7.50 a month on the annual plan.
How is Rivie different from other SAT prep?
Rivie matches every question you miss to the mistake it was written to catch, then plans your practice around the mistakes that cost you the most points.
How much time do I need each day?
As much as you have. Set your daily minutes and your plan fits each day to them, starting with your biggest mistakes and any questions due for review.
Do I have to take a full practice test first?
No, but it is the fastest way to a useful plan, because one test covers every topic. You can also start in the question bank, and your plan builds from whatever you answer.
How accurate is the scaled score?
College Board does not publish its scoring formula, so Rivie’s is fitted to real scored results. Your report shows a score range rather than a single number.
Where do the questions come from?
The ten full-length tests are 1,470 original questions, written and reviewed in-house to the College Board blueprint. Each one is tagged with the mistake it tests. Rivie is not affiliated with College Board.
