Forgetting is normal

We forget things - no matter how much we try, we will forget at some point. Forgetting is not bad, it’s part of learning process. Make note so that you can quickly recall after forgetting.

Brain betrays, notes do not

How many time did you face a situation where you need to recall some important memory/knowledge but could not? Even though you are sure that you learned and mastered it, but could not just simply recall it when needed. Your brain just betrayed you. Make friend with notes, they will help you when you brain betrays, LoL.

Write down what you learn

Writing down after learning reenforces memorization. It also helps to express and establish you’r own way of learning.

Create cheatsheets

Cheatsheets are short version (summary) of your learning course. When you are supposed to apply some knowledge after learning, cheatsheets help to be productive.
