How often sololearn repeats same questions in play?(quiz)

Answer 1

I think it depends on language to language. For example in C quizzes I hardly see any repetition whereas in C++ quizzes I have seen a lot of questions repeating quite frequently.

Answer 2

For me they repeat often like I can do a challenge and get the same question in the next one but I don't think it applies for all languages like php I haven't yet seen any repeated questions
