All Kata is diverse, some require a lot of knowledge about the language. What resource would you recommend for more language learning?

If the errors are not traceables but because of the test, then the test conditions must be met, which are sometimes not written in the instructions.

Thank you for your reply! That makes a lot of sense.

IIRC, you can unlock solutions only to those katas which are at most 1 kyu above your current level.

Is the unlock solution button only available for 8 kyu and 7 kyu? I'm stuck on a problem and I'm looking to understand the solutions to the 5 kyu problem but I can't find the button on the bottom to forfeit the honor for the kata I'm on and unlock the solutions
