Yes, you can. If you score less, your score does not change. If you score higher, it retains the higher score. Of course, you won't change the 100 points that you received for watching the video the first time. You may re-watch the video as many times as you wish. Download it and watch it at your convenience.
Of course, I wouldn't recommend doing the quiz over and over to increase your score. The scores are meaningless. Only repeat the quizzes if they help you understand the lesson better.
Hola , If I understood your question I should say you can replay the videos and take notes simply . and when you are taking flashcards quiz there is an option "retry flashcards " whenever you get more points the new points will be recorded
