I'm building a website where students can create online study groups to share goals, notes & flashcards. Would love some feedback!

Hey folks, I am still building this sort of all-in-one group learning tool and I was wondering if you could give me some feedback on it.

Here is the demo (you can watch it at 2x speed) https://youtu.be/fExuceuRF5o

Would love to hear your thoughts. Is it something you would use at college? Or to self learn?
