Help and Instructions

Welcome to Learn Kap. Solve the programming problems by typing into the input box. You might want to open the Kap Reference to another tab.

Some problems are solvable with one symbol only, so for example this is perfectly fine: myFun ⇐ ⌽

Use the arrow buttons to navigate between questions.

Click the "Check" button to check your answer.

You can skip up to 2 questions by clicking the forward arrow without answering.

The grid at the bottom shows the status of each question: green = correct, red = incorrect, yellow = skipped.

Learn Kap is under development. Known issues:

• Storage gets sometimes corrupted and you will see it as questions not loading. You have to click "Restart" and then load the page again. Be sure to write down your answers for yourself!
• Kap is not super optimized yet with large arrays. When you click "check" it might take time for it to turn green. So just wait a few seconds.
