Past papers are not hard to find, greenbooks and PDFs are everywhere. What is hard is knowing which ones you have already done, which you failed, and what to revise next.
Danho tracks that instead of leaving it to memory. Every paper you sit becomes a row: sat, passed, or still to try. Every incorrect answer joins a revision pile that only clears when you get it right.
The question bank is drawn from real ZIMSEC O Level and A Level past papers, with worked explanations wherever one exists and a source reference back to the original paper when it doesn't.
