01 · UPLOAD

Drop in PDFs, slides, worksheets, photos or pasted notes. ArcStudy reads everything you actually study from.

02 · DIAGNOSE

A short diagnostic stress-tests every concept — not for a grade, but to find what you genuinely don't know.

03 · TRAIN

Short targeted sessions hit your weakest concepts first, with explanations that simplify when you struggle.

04 · TEST

Professor Mode builds a realistic exam from your own material, and gets harder as you get better.

05 · MASTER

Mastery scores climb per concept. Gaps close. You walk into the exam knowing exactly where you stand.

The one question ArcStudy always answers

"What do I need to learn next?"

A student can score 80% overall and still be badly weak in one concept that's worth 15% of the final. ArcStudy tracks accuracy, difficulty, confidence, timing and repeated mistakes per concept — so the weak one never hides behind the average.

🔥 Am I Cooked?

An honest readiness score before the exam, plus the two areas that would move it most.

Professor Mode

10, 25 or 50-question practice exams generated around your own material.

Teach Me

You explain the concept back. ArcStudy tells you what you got right and what you left out.

Last Minute Mode 💀

Tell it how long you have. It builds a minute-by-minute cram plan around your weakest topics.

Stop studying everything. Start studying what matters.

Every feature is free — no plans, no limits, no paywalls.
