For parents

More practice. Better test day.

The best way to get ready for a test is to practice taking it. TestDupe gives your kid as many fresh rounds as they need.

Practice the real thing

Each dupe matches the test they're studying for: same skills, same format, same difficulty.

New numbers every round

They can't just remember the answers. Every round makes them work each problem again.

Find the weak spots early

Missed questions show which skills need another round, before test day instead of after.

Walk in confident

By test day they've already done it a few times. The questions feel familiar, not scary.

You took the practice test.
