How do you best understand and explain information?

through writing, speech, diagrams, memorization, paragraph form, point form, acronyms, any other method?

Personally, I like explaining thing with diagrams, but there is rarely a pen and paper in sight, and no one wants to waste their time with that. I like guiding them through it.

I understand better with diagrams too. If I’m in a class where it’s completely auditory and no visual, I’ll be as dumb as my left foot.
