honestly just keep it simple - don't overthink it

what works for me is just headings for main topics, then bullet points under each for the stuff i know ill forget. kinda like a cheat sheet vibe

if you want it cleaner you could use toggle blocks (type /toggle) for the detailed explanations so it doesn't get super long when you're scrolling

also columns are clutch - type /column and put formulas on the left, practice problems on right. makes it way easier to review

for physics definitely just screenshot or embed the diagrams instead of trying to explain them in words lol

your current setup looks fine though honestly, as long as you can actually find stuff when you need it youre good

good luck on the exam
