10 Tips to Study Smarter




1.         The foundation: a productivity system

Our first tip therefore is to adopt a productivity system. You need to develop the habit of consistent and effective note-taking, you need to have a clean, uncluttered desk to study at, you need a system for storing reference material and tracking your (learning) projects. I strongly suggest following this important tip, because it will make everything else (including learning) more efficient and effective.

2.         Speed reading

 You probably need or want to read a lot of offline and online material as well. But you only have so much time to do it. This is where my second tip comes in. Practice speed reading to read smarter and faster, while improving your comprehension

3.         Think and work on paper

There is no question that pen and paper are the most underrated productivity and learning tools around. My advice is to always think and work on paper. It will get things off your mind and make room for more creative thinking. Use your own shorthand and notational system to highlight important facts and actions in the material you’re learning. Condense, memorize and review the material you’ve learned by creating mind maps.

4.         Use multisensory techniques

 This tip is all about discovering your preferred learning style and leveraging it to make learning more fun and more effective. You have to figure out for yourself if you are more of a visual learner, an auditory learner or a kinesthetic/tactile learner. Information will be absorbed by your brain much quicker and much more effective if you use your preferred learning style. To enhance your learning experience even further, combine your preferred learning style with the other ones. For instance, writing things down combines the visual and tactile learning styles. Reading things aloud to you combines the visual and auditory learning styles

5.         Allow your brain to absorb new stuff

Everybody has a certain learning rhythm. Some learn best in the early hours of the morning, others learn best late at night. Figure out which rhythm and time frame suits you best and use this to maximize your learning ability. However, you must frequently give your brain time to absorb the new stuff that you are learning. The best way is to “sleep on it” and the second best way is to take frequent breaks and do something completely different.

6.         Learning is in Your Head
Having beautiful notes and a perfectly highlighted textbook doesn’t matter if you don’t understand the information in it. Your only goal is to understand the information so it will stick with you for assignments, tests and life. Don’t be afraid to get messy when scrawling out ideas on paper and connecting them in your head. Use notes and books as a medium for learning rather than an end result.

7.         Food for thought: Eat breakfast.

A lot of people skip breakfast, but creativity is often optimal in the early morning and it helps to have some protein in you to feed your brain. A lack of protein can actually cause headaches. Eat a light lunch. Heavy lunches have a tendency to make people drowsy. While you could turn this to your advantage by taking a “thinking nap”, most people haven’t learned how.

8.         Reduce stress + depression.

Stress and depression may reduce the ability to recall information and thus inhibit learning. Sometimes, all you need to reduce depression is more white light and fewer refined foods.

9.         Focus and immerse yourself.
Focus on whatever you’re studying. Don’t try to watch TV at the same time or worry yourself about other things. Anxiety does not make for absorption of information and ideas.

10.         Persist.
Don’t give up learning in the face of intimidating tasks. Anything one human being can learn, most others can as well. Wasn’t it Einstein that said, “Genius is 1% inspiration and 99% perspiration”? Thomas Edison said it, too.
