Built to help your students, not replace you
NailTheTest is a free precalculus study tool your students can use alongside your class. It reinforces your teaching with visual explanations, adaptive practice, and a private tutor that follows the same curriculum you do.
Supplements, never replaces
NailTheTest reinforces what you teach. Students get extra practice, worked examples, and AI explanations — all aligned to your textbook.
Aligned to your curriculum
Students select their textbook and see exactly which NailTheTest sections match their class. Covers Stewart, Blitzer, Sullivan, Larson, OpenStax, and more.
24/7 private tutor backup
The private tutor explains concepts at 11pm when you can't. Socratic method - it adapts to each student and guides them to understanding, never just gives answers.
Students track their own progress
Mastery scores, spaced repetition, study streaks. Students see where they're strong and where they need work — no extra grading for you.
Exam prep that works
Exam Mode simulates real test conditions: timed, no hints. Students can practice before your tests without you having to create extra material.
Free tier is genuinely useful
All concept explanations, diagrams, worked examples, and worksheets are free forever. Students who want unlimited practice and private tutoring can upgrade for $59.
