Fromis9's question (3)

Do you have any studying style/technique that doesn't require too much pretentious preparation?

I don't really trust ytubers that enforces this "you must have this differently colored pens and papers" or "you must have this expensive gadget" like chile

even if it's a small thing or something big

Y'all must have your favorites but pick out the best 1 that you will always recommend. I don't care what genre it is. It can be popular or not.
