Our story: building the future of test prep

We're more than test prep. Born from Finnish research, we pioneer a science-based approach that transforms how students learn and succeed.

How it all started

We started as a small but determined team in Finland, challenging major educational publishers who had long controlled the high school market. Starting with a tiny marketing budget, a handful of hardworking people, and no institutional backing, we focused on one thing: building a better learning experience.

The results speak for themselves. We saw a meteoric rise, becoming the go-to choice for medical school entrance exam prep, with 67% of all successful applicants relying on our courses in 2024.

SAT practice exam with multiple choice questions

Perhaps even more impressive, 50% of all high school students in Finland preparing for their math finals choose us — most buying our courses themselves despite their school offering another product for free.

Exceptional results drove exponential growth that lead our company to grow to be a market leader in entrance exam preparation and to claim our spot as one of the big players in the Finnish educational publishing industry.

We don't just create SAT® content. We build science-based, student-tested learning experiences using the methods we pioneered in Finland
