Do you think it's more efficient to make handwritten study/reading notes on looseleaf paper kept in a binder or make them in a notebook?
It really depends on personal preference. The key to both is having a system of organisation. Without that, both are shit.
In a notebook, the best organisation method I’ve found so far is borrowed from bullet journalling. Make an index at the start, manually number your pages, and add topics to the index as you go. I’ve started this recently for a journal keeping notes on the plants I acquire (they’re starting to be so numerous that I can’t remember sun/feeding/watering requirements off the top of my head).
In a binder, organisation strategies are a bit more intuitive - use section dividers, side tabs, title pages etc.
The pros and cons of both systems, as I see them:
Binder pros: flexibility (can re-order pages as you develop a better understanding of the knowledge, can add more pages if you run out or cycle out finished materials. You can also remove sections at a time to study, which is great if, like me, you like to pace around. Hole-punch sounds (v satisfying). Binder cons: in my experience, they’re less portable (much easier for the binding to open and spill your pages everywhere, also they tend to be large and unwieldy). Also a little less aesthetically pleasing than a notebook (that’s my personal take, though).
Notebook pros: portable, can look lovely, sense of satisfaction when you fill them. Notebook cons: Less flexible in how you organise them (can be overcome, to an extent, with a good index)
My ~~ultimate recommendations~, if you want them, are as follows (bear in mind that I generally type my notes so give this advice on a hypothetical if-I-handwrote-notes basis). Take a notebook to class to take rough notes etc., organise these notes meticulously with index etc. When condensing and organising these notes to make summaries for study, start a binder that stays at home, more or less, from which you pull certain sections to carry around as needed.
Hope this helped! At the end of the day, though, you do you. If it works for you, it’s a good system.
