The Skill Test

Learn C Programming Skill Test

One timed test that shows what you can do in Learn C Programming: concepts, reading and fixing code, and writing programs that pass hidden tests. Every question can be answered from the free and core lessons.

Three sections

  • Concepts25 questions, 30% of the score
  • Read and debug5 questions, 30% of the score
  • Build3 questions, 40% of the score

Score is 0 to 1000, across three sections: concepts, read and debug, build.

Before you start

  • 90 minutes on one clock. The test runs in fullscreen, and leaving the tab is recorded.
  • Questions are drawn at random from a large pool, so two people rarely see the same paper.
  • Your code runs against hidden tests. Build questions earn partial credit for every test passed.
  • There are 14 days between attempts on a track, the free one included.
  • Starting uses the attempt, even if you leave before the end.
