How did you organise your notes at uni?

I study maths at uni, and im starting my 2nd year soon. I used to use my ipad in the 1st year but that's broken now, so I'm resorting to pen and paper. I'm wondering how I'll organise my notes. I have 4 modules, and each module has lectures and seminars, I'm thinking of getting these spiral notebooks so I can fold them in when writing, that meals I'll have to get 8 spiral notebooks, I'd also like a revision notebook per module, so thats 12 spiral notebooks. But I don't know if having 3 books per module would get annoying to manage. Another thing is thst I can have 1 slim ring binder per module and then seperate lectores, tutorials and revision using dividers, and write on loose leaf paper during lectures and out them in my ring binders at uni. What would you guys recommend? I see most people use spiral notebooks at uni as opposed to loose leaf paper.
