Secret #7: REVISE! REVISE! REVISE!

If you revise, you'll improve your learning by 100%.

What does "to revise" mean? It means "to read again".
You should be systematic about this. When you learn
something, you should note it. Then you should *look at
it again*, 3 times:
- after 1 day
- after 1 week
- after 1 month

Each time you revise, test yourself.

Learn, revise, test.
Revise, test.
Revise, test.

NOTE:
revise (BrE): read again to improve one's knowledge
revise (BrE & AmE): read and correct; update
