When trying to study. . eating a piece of dark chocolate lights up the brain with all the good stuff that helps you remember
What you just read.
So grab a hunk
Also..
If you’ve just learned something and want to retain it.
Take a 20 minute nap.
Subconsciously , the mind will work to retain all that you’ve just learned faster. Than. .if you say.. stayed awake.
Chewing gum during testing .
Helps your brain recall things you’ve studied.
Chewing something with peppermint is the best combination ..
Do that.
