Tell me some tips so that I can learn it very fast.

Hello. I can share my case with you. I learn quickly and efficiently. I developed my own personal method. What is its essence? In fact, I need to remember the material, to understand where I will use it. If you just need to learn something because you need to earn a grade at the university, then it is better to turn to https://www.reddit.com/r/essay_helpers/comments/vdmqh0/domyessay_reddit_review_2022_my_experience/ and if you need to expediently understand the material, then the first thing to do is start reading. Watch videos, read articles. Then, over time, think about what you have already understood from what you have read. Then I recommend that you tell the material to your friends or fellow students. This way you can better understand and consolidate what you read. Good luck!
