We speak your (coding) language
Play quizzes in your favourite language and practice the programming skills that you want to sharpen. Our coding quizzes are made by the community and also include special quizzes created by some of the top developers on the web.
Practice makes perfect
Was it .slice() or .splice()? Even the best developers in the world get stuck sometimes: reach for a common method then realize there’s a similarly-named function and they can’t remember exactly which is which..
Use Kwiz to practice the areas that you need to strengthen. You can save your favourite (or most frustrating) quizzes and practice them when you have spare time or as part of your daily coding practice.
Real code & syntax highlighting
We use rich syntax highlighting & real code blocks in all of our quizzes - no more screenshots!
When you create a quiz using our Kwiz Creator you get real formatting with friendly tabs and proper code blocks. Copy & paste code like the pros :)
