How can make notes quickly and easily?

We had a English class this morning . it is about making notes . but I didn’t known it very well, and I can’t do it well. I wanted to know how to do it quickly and easily.I need some help.

write down what is important and if there is a lot of stuff shorten the words for example:

you need to know how the novel was first introduced to society.

translated to “note” talking, how i write it anyway.

u need 2 know - how was book first known

any word that can be symbolized like the word to put a 2, sounds the same, all that matters but if you aren’t that good at english i recommend you practice a bit hehe
