Good to know
- Do I need to install anything?
- No. Everything runs in your browser: Python via Pyodide, C and C++ via a Clang compiler built for WebAssembly (a one-time ~23 MB download), and JavaScript natively. Run checks the samples; Submit checks the hidden tests.
- What is free?
- All 15 Easy coding problems, the first full mock and quick test for every company, and the prep kits. Campus passes unlock the rest.
- Are the mocks like the real tests?
- Sections, timing and question styles follow each company’s recent pattern. Real papers change every season, so treat these as practice, not leaked papers.
- Where is my progress saved?
- Coding progress and drafts are saved on this device. Your best results go to the leaderboard when you are signed in.
