Choose Exam Mode to sit a timed session under real exam conditions, or use the graded mode where PaperStack Intelligence scores your structured answers directly against the marking scheme.

Interactive MCQ Solver
Solve MCQs directly on screen. No printer needed. Auto-marking gives you instant feedback and saves your progress as you go.

### 5/5 — 100% would recommend

*2026-05-31*

This is probably the best app out there for solving past papers especially for MCQ. The live checker is the best feature tbh. I don’t know why it hasn’t gained more attention, but I’ve already recommended it to my friends 👍

**Developer response:** thankyou & glad paperstack helped you!!
