Repetition tasks

Hello :) I just had an idea that repetition tasks for already completed courses are a good addition to the study journey. It Would give a great additional value for your brain. Especially it would be nice if you can also select the courses and then the questions are aligned accordingly. Or just completely random from different courses. How you want to do that is up to you anyway. I just noticed that this is really beneficial for practicing. Because we all know, repetition is key!
