Marty Lobdell - Study Less Study Smart - YT video

1. Don’t study for too long if you are not enjoying it. Take short breaks after 20-30 minutes.
2. Don’t study in the living room, bedroom, etc. Study in a separate place dedicated to studying.
3. Don’t try to memorize without understanding. Try to understand the concept first.
4. Don’t always study alone. Studying in groups helps a lot.
5. Don’t highlight text blindly. Highlighting doesn’t help that much. It only indicates Recognization not Recollection of the topic.
6. Always take notes. Reviewing the notes after a short time helps a lot.
7. Always try to teach others what you have learned. Teaching is the best way of learning.
8. Sleep is so much important for pushing something into your long-term memory. Get at least 7-8 hours of sound sleep.
