The tests at the end of python lessons.
I have been learning python for a couple days now but I have run into only one thing that I consider an issue and that is, at the end of my lessons there is a quiz of sorts... it seems as if you cannot complete these quizes. I learn the concept and do the problem correctly! it even says that I do. The issue is that every time I complete 1 there are 3 others that are similar so I try to complete them as well but.... as soon as I go to write a code for the next problem, it indicates that the previous problem has yet to be solved eventhough I solved it but it seems like as soon as I move on from that problem it tells me that it needs to be redone... so therefore I have been unable to complete all three problems to pass the quiz. This has happened to me on most of the quizez making me unable to complete them, i do not understand if anyone has any answers they would be much appreciated.
