What do students say about Dolphin?

• I used to check the right answer and move on. Dolphin's explanations helped me understand where I went wrong. After a few months of actually reviewing my mistakes, I went from 1100 to 1320.

  Maya, Junior: SAT 1100 to 1320

• Between soccer and homework, I kept putting SAT prep off. Having practice on my phone made it easier to fit in a few questions. I went from 1230 to 1400 on my next test.

  Ethan, Senior: SAT 1230 to 1400

• Math was definitely my weakest section. Being able to work through the explanations at my own pace helped things finally click. It took a whole semester, but getting a 1250 after starting at 980 felt amazing.

  Sofia, Junior: SAT 980 to 1250

Why I built Dolphin

I built Dolphin because I saw what test prep was doing to my younger sisters. They were using random tools, trying to care, and still ending up frustrated. I wanted to build something students would actually open, actually use, and actually learn from.
