In fact, everyone can improve memory with simple methods. First, connect new knowledge with old knowledge. Our brain stores memory like chains. When you link new words or rules with things you already know, they will turn into long-term memory easily. If you mix up similar words, draw different pictures for each word to tell them apart. Second, review properly and don’t overstudy. Forty minutes of study is enough for one round. If you keep studying for hours, you will wear out your brain. You can discuss knowledge with classmates or teach others to review information. Third, use your senses. Mind maps, graphs, stories and listening materials all help build clear images in your mind. These methods are far more effective than reading text repeatedly. Last but not least, keep healthy. Sleep helps the brain organize memories at night. Healthy food works as fuel for your brain, and exercise makes your mind active. There is no one-size-fits-all memory skill. You can try different ways and find the best one for yourself. 1.
