Computers don't forget information they are given, but humans often do. No one remembers everything, and luckily we don't usually have to. But everyone can improve their memory if they want to. Here are some suggestions.

◆Write out what you need to remember over and over again. This will help you keep it in mind longer, especially for memorizing formulas (公式) or facts.
