In many social sciences, I have to know the context. Like in history, if I’m learning about the great, I remember that the 1920s were very good times, and then the crash happened in October (all major economic crashes happen in October by coincidence, or not), and then I think of the president who was in that time period. There was too little government intervention, something that republicans prefer, so he was a republican president, so I think of Hoover. Then, to correct this mistake, they elect a democrat president, Roosevelt, and they liked him so much they kept him for 4 terms. I just memorized so many facts from such a little amount of information. Like a chain reaction.
If it’s math, I’ll fail anyways.
If it’s chemistry, know the equations and nomenclature, and how to figure out the chemical equations. And units are important too.
Languages, I have to say it in my head, and I “see” the letters in my head.
Many other things are cause and effect, like a big chain reaction. This works for memorizing things. Like A causes B, and B causes C, and C causes D, so A is indirectly responsible for D.
