So I've been trying to get through the CodeHS certification for about four months now and honestly it's been humbling. First attempt I scored a 61%, second time a 67%. Both times I felt like I understood the material during the course but then blanked on actual test questions. The logic problems and debugging sections just destroyed me.
What finally clicked was finding a solid CODEHS practice test that actually matched the format — not just random coding trivia. I also went through a structured study guide that broke down control structures, functions, and object-oriented concepts separately instead of all at once. Spent about 90 minutes a day for three weeks before my third attempt.
Passed with a 79%. Not amazing, but I'll take it. My biggest exam tips for anyone else struggling: don't just read the material, actually trace through every code snippet by hand. The tricky questions are about predicting output, not just knowing syntax. Anyone else have sections they found unexpectedly hard?
