Get ready for coding interviews, exams and skill tests with CodeQuiz. Practise more than 3,800 multiple-choice questions across 58 programming languages, frameworks, cloud platforms, databases and developer tools, and see exactly where you stand.

Practise with instant feedback and 50/50 hints, take a timed exam, or study a topic at your own pace. A daily challenge, a speed round, interview prep for roles such as Android, iOS or frontend developer, and learning paths keep practice varied, and the questions you got wrong come back until you master them.

Track your accuracy, weekly activity and mastery for every topic, keep a streak and a daily goal, and earn a certificate to share when you score 80% or more. There is no account and no sign-up: the questions are built into the app and your progress stays on your phone, with backup and restore to a file of your choice.
