Why Choose Our SAT® or ACT® Test?

Make assessments

AI and education experts teamed up for a better way to prepare for tests. We believe the purpose of tests is to facilitate learning, not to stress test-takers.

OUR APPROACH

Shorter, yet deeper

Our Fast CAT algorithm adaptively selects a set of questions that can best assess a student’s test preparedness. It drastically reduces the time taken to evaluate student knowledge, while providing deep insights.

BIGGER MISSION

One step closer to equity in education

What makes AI special in education is that it allows us to provide things that are tailored to an individual’s specific needs, the things that are potentially more costly.
Jason Park
AI Research Scientist
We assess students not to judge the result, but to help them learn better throughout their learning process. We leverage AI to capture things that are unnoticed by humans.
David Loh
AI Research Scientist
To bring true innovation to education and address the exponential demand for personalization, AI is the key ingredient. And we are ready to lead this transformation.
YJ Jang
CEO & Founder
High-stakes testing has widened the education gap across socioeconomic lines. We developed R.test to help students overcome this barrier regardless of their backgrounds.
Jason Kang
Content Lab Manager
I believe that the ultimate goal of education is realizing the highest potential of each student. Education should help students realize that they can achieve more than they think.
Sam Kim
Machine Learning Scientist
AI-driven education is here to stay. And with the pioneering efforts of global leaders like the R.test team, it can become a reality for all students.
Ju-ho Lee
Education Minister and Deputy Prime Minister of South Korea
The research quality is among the top 25% of all papers accepted to AAAI. This research will surely be popular in the next years.
AAAI
Association for the Advancement of Artificial Intelligence
They are driving a paradigm shift in education from a ‘one-size-fits-all’ approach to personalized instruction. We are delighted to support their vision for quality education.
