Say it out loud - Studies show that reading the information you want stored out loud can increase your chances of remembering it by 50 percent.
Reward yourself - Your brain can learn to attach itself to almost anything. If your brain thinks something makes you happy, it is more likely to throw it in the important memory basket.
Draw it out - If you need to remember a process in order, draw it out as a flowchart. If you need to remember people, sketch out notable characteristics.
Catch some zzz's - Getting enough sleep is so important for remembering information. Sleep consolidates a memory so it can be retained quickly in the future.
Study with a group - If a particular theory is confusing or a certain era is overwhelming, there’s a high chance that someone in your study group will have a good grasp on it.
Chunk it - Breaking long streams of information into manageable chunks gives your short-term memory a better chance at storing it.
Wiggle your eyes - It may sound odd, but moving your eyes from left to right and from right to left is one of the easiest way to enhance your memory before a big test.
