  • Maybe you aren't... yet. But with Happi, you will be.

    Happi is designed to fit a range of starting levels—from students struggling with math in their first year of high school to math whizzes aiming for those last 20 points on the SAT® math section. Happi systematically guides you through the SAT® math curriculum and its prerequisites, adapting to your level as you progress.

  • In addition to the SAT® math curriculum, Happi teaches you everything you need to know about using Desmos. Whenever Desmos is useful in solving a problem, we have shown how to use it in the model solution.

  • Definitely! While less than 1% of SAT® exam takers score the max points, making it exceptional, that doesn't mean it's impossible!

    Success in studying is not about who you are, but rather the method you use, combined with persistence in following the method. One of our students improved their score from 730 to 790 using Happi – and that was done with only 34 hours of studying!*

    *Results are not guaranteed and all results will vary by individual.

  • Everyone is different. Your rate of progress depends on your starting level and how consistently and diligently you study. It's important to remember that even slow progress is better than no progress at all.

    Studying with Happi is extremely simple. Let the app guide you, and it will give you the best chances of making progress. The rest—studying consistently and diligently, and taking care of yourself—that's up to you.
