Trying to go through the learning paths again is not a fun experience since the answers to the quizzes in the end remain filled in. I feel like there is no benefit to them being saved and should be empty everytime you open them, or there should be a button at the start of every learning path to clear them so you can do them again
I think this would be a good idea as an option to clear history, especially for non exam based learning paths where you want to refresh your knowledge after a period of time. This would allow you to track progress back thropugh the path and also be able to ensure quetions fresh
Well normally you take the exam again if you failed, so then you see the wrong answers you gave at first. This way you learn from your mistake. But if you redo the learning paths after a while or after you had allready passed, then yeah might be better to empty it.
