Ooof. I know how you feel. Generally, I try to get my friends to study at the same time (drag them to the library with me) so I feel a bit more motivated. If I have a major thing to work on I bribe them with cookies to help me out or etc.

I don't know about you but my school has tutoring services and study skill help so you might want to sign up for those.

But yeah, I tend to misremember a lot of meetings and classes and my memory was spotty to begin with so it's just infinitely harder when you can't trust your brain. I personally ended up having to drop a few classes to try and save the others but I hope you don't have to do that.

Best of luck!
