According to research we remember
10% of what we Read
20% of what we Hear
30% of what we See & Hear
50% of what we Discuss with others
75% of what we Experience ourselves
and a staggering 90% of what we TEACH to someone else.
So the best way to get a grip on a topic is to TEACH the same to someone else. This forces your brain to connect the dots and helps you imbibe the knowledge in a manner where you understand the topic and are able to explain it to others in your own words.

So go forth share your knowledge with others, it will actually benefit you more than the those being taught. It will help you understand and retain that topic much better.
