This is advice from a medicated, daydreaming, innattentive serial procrastinator:

Collegeruled spiralbound notebooks, the three thick ones--get one for each class. Since you're hitting the end of the semester, you could probably deal with the regular ones.

Whether it's Zoom lectures or just pre-recorded bullshit, pretend you're on camera while you're watching it. You're obviously lying to yourself, but dismiss that. Now you're being held accountable, and have to at least look like you're paying attention (even if you're hyperfocused on the shape of a suddenly very interesting speck of dust on your computer screen).

Write notes. Just write them. It fucking sucks, but it's imperative. I have damn near novels worth of notes that I've taken. Mix it up with different pens of different colors, and attempt to make it exciting.. because it's not exciting. I have a thing with office supplies though that might not translate over for other people. Draw things you need to understand and label them with them, do whatever. If you have instruction materials that are pausible, take advantage of that. If all of your shit is mostly reading chapters, I'm sorry from the bottom of my heart. I've thrown myself around in a tantrum of despair over this because of how soul destroyingly boring it is (note: do not let others see you do this. Throw your grown ass adult boredom hissy alone and never admit to it. It's yours alone to treasure).
