See What Our Students Say

93%

R.test helps prepare for tests efficiently

“felt much shorter than I expected.”

It’s a really fast and efficient way to calculate your score. The diagnostic test is just about 10 questions per section, so it felt much shorter than I expected and yet it still seems accurate.

Edward, 11th grade

“perfect tool to practice for digital SAT”

This is a perfect tool to practice for the digital SAT. I highly recommend this to students and tutors who need to be ready for the SAT format changes next year.

Joon, SAT tutor

87%

Predicted score is accurate

“tells you exactly what you need to work on.”

R.test’s report is totally different from other reports I’ve seen before. Others only give a score, but this gives you a detailed report that tells you what exactly you need to work on.

Nehemiah, 11th grade

“enables me to provide personal guidance ”

As a counselor who looks over dozens of students, pointing to the ‘Top 3 areas for improvement’ is a really helpful feature. It enables me to provide personal guidance to my students in a limited time.

KJ, counselor

81%

Would recommend R.test to peers

“very close to official sets”

The diagnostic test takes less than an hour so it’s a great way to check up on a student’s capability before the actual test. There are not many quality practice sets out there, but this is very close to official sets.

Brian, SAT tutor

“quick, easy, and accessible”

I would recommend this to students new to SAT to casually check their scores without spending too much effort and cost. R.test is quick, easy, and accessible.

August, counselor
