That sounds hard, a video lecture! My online classes don't have any video, just reading and writing and it can all be printed out, etc. Good luck, Gus, but sounds like you have a situation any of us would find hard.

I know when I was take the National Archives "course" to get a reader's card in London, they threw in quizzes every few points and I kept doing poorly on those and panicking, thinking I would not get the card but, fortunately, they made you keep trying to answer until you guessed the right one before they would move on. Would it help to write things down/take notes as they lecture or are you already doing that?
