You have a responsibility to learn yourself. I don't know if you mean you missed the lectures yourself, or if they were canceled for some reason, but it doesn't matter, it is still your responsibility to learn. It sucks if it is not your fault of course, but it is not an excuse for not learning since you're not at college for any reason other than learning.
But I'm not objecting to that. I'm objecting at coming here and asking for a solution. We don't allow that here at GameDev. You ask for answers about problems, not for solutions to tasks.
I was at a university, partly as a student of course, but mostly as a teacher for post-graduate level courses, for around 15 years now. I see this behavior a lot, and it really is the one of the worst ways of learning. That is why I am so reluctant to provide any assistance on the project, but rather advise you to truly study and learn, because I have seen enough student fail with the kind of approach you're showing. You're only cheating yourself, and it will come back at you.
