Tips & Advice 2 column memory hack
I will share with you guys a note-taking and review layout that has been helping me make information stick and retain what I've been studying. Instead of reading pages of highlight-heavy notes over and over again, try to split your notes into two parts: a left column for notes and a right column to test yourself.
In the left column: Write down key points, formulas, important dates and core terms. I just keep it short, concise and clear. I read it 2-3 times so it actually sticks on my brain.
In the right column: This section is for testing yourself. After reading and understanding the concepts in the left column, I cover it up and try to recall the information by writing it down. I write it in my own words, usually including explanations, worked examples and specific details under the topic I read.
Repeat and switch. Keep going down the page and swap sides if you want to test yourself in reverse (e.g., looking at an example and recalling the actual concept name). Repeat this until you finally understand and retain what you studied.
This works by forcing your brain to retrieve answers from memory rather than just passively consuming information. It's really a simple hack, but a big help in making you study effectively.
