Practice

Where the practice actually happens

Watching lessons is the easy part. These two decide whether you are still solving problems in month three.

Progsity Playground running a C program in the browser, with the code editor on the left and the output panel on the right showing Hello, World! and an Accepted verdict.
Try it yourself

Progsity Playground

Run C and C++ straight in the browser, editor on one side, output and standard input on the other. Nothing to install, so trying an idea never waits on a working compiler.

XP, streaks, badges and a weekly leaderboard

Every lesson, quiz and solved problem earns XP, which raises your level and unlocks badges, sixteen of them, from First Steps to a hundred-day streak. Each week you also see where you stand against the rest of your batch.
