• Use recall. When you look at a passage and try to study it,  look away and recall the main ideas. Try recalling concepts when you are walking to class or in a different room from where you originally learned it. An ability to recall—to generate the ideas from inside yourself—is one of the key indicators of good learning.
• Test yourself. On everything. All the time. Flashcards are your best friend. Use quizlet if you don’t want to hand-make flashcards. Get somebody to test you on your notes.
• Space your repetition. Spread out your learning in any subject a little every day, just like an athlete. Don’t sit and study one subject for 2 hours, do half an hour every day.
• Take breaks. It is common to be unable to solve problems or figure out concepts in math or science the first time you encounter them. This is why a little study every day is much better than a lot of studying all at once. When you get frustrated, take a break so that another part of your mind can take over and work in the background. You need breaks in order for your brain to retain the information. Try the Pomodoro method if you have trouble timing breaks!
• Use simple analogies. Whenever you are struggling with a concept, think to yourself, How can I explain this so that a ten-year-old could understand it? Using an analogy really helps. Say it out loud, like you’re teaching it, whether it’s to an imaginary class or your sister who couldn’t care less.  The additional effort of teaching out loud allows you to more deeply encode.
• Focus. Turn off your phone / iPad / any distractions and clear your desk of everything you do not need. Use apps like Forest if you can’t stay off them!
• Do the hardest thing earliest in the day, when you’re wide awake and less likely to push it aside.

• Passive rereading—sitting passively and running your eyes back over a page. This is a waste of time, frankly, and doesn’t do anything to help information pass into your brain without recall.
• Over-highlighting. Colouring a passage of text in highlighter isn’t helpful at all. It’s good for flagging up key points to trigger concepts and information, but make sure what you highlight goes in.
• Waiting until the last minute to study. DON’T CRAM!!!
• Doing what you know. This isn’t studying! This is like learning how to juggle but only throwing one ball. 
• Neglecting the textbook. Would you dive into a pool before you knew how to swim? The textbook is your swimming instructor—it guides you toward the answers. 
• Not asking your teachers for help. They are used to lost students coming in for guidance—it’s their job to help you. 
• Not getting enough sleep. Your brain practices and repeats whatever you put in mind before you go to sleep, as well as retaining information and repairing itself. Prolonged fatigue allows toxins to build up in the brain that disrupts the neural connections you need to think quickly and well.
