Built around the work
we do every day.
VindicaOS grew out of a working SAT academy in Korea. The same practical questions shaped it: who needs attention, what should we teach next, and how do we explain progress to parents?
Mocks, practice, live classes, and reports belong together. VindicaOS gives your team that shared view, under your academy's own name.

Before you begin.
Is there a setup or onboarding fee?
No. You import your students and run your first mock the same afternoon. No setup fee, and no annual contract.
Do you charge per test or per mock?
No. $10.99 per active student covers unlimited mocks, practice, homework, and reports. Your bill does not change because a student took another test.
What is in the free workspace?
The full product with a demo student who already has practice history, mock scores, and reports, so you can try the whole workflow without inviting anyone. No card is needed. Billing starts only when you add a real student.
How is this different from a test-hosting platform?
Those host tests. VindicaOS tracks mock results, groups each student's misses by skill, suggests a next focus, and carries that into practice sets, classroom review, and parent reports, all in one place.
Can we run it under our own brand?
Yes. Your name, your color, your domain, at no extra cost. Students and parents see your academy, not us.
How is the quality of the questions?
Every item is original, written to real Bluebook difficulty and format, and put through a multi-stage authoring and review process before it reaches a student. Each one arrives tagged by skill, and you can layer your own questions on top.
We're a nonprofit school. Is it really free?
Yes. Qualifying nonprofits and under-resourced schools get the same platform at no cost after a light eligibility check.
Is our students' data safe?
Each academy's data is isolated at the database level, encrypted in transit and at rest, and never sold. You control the student data and can request an export or deletion under our binding Data Processing Agreement. See how we handle data.
