Listen to music. Researchers have long shown that certain types of music are a great “key” for recalling memories. Information learned while listening to a particular song or collection can often be recalled simply by “playing” the songs mentally.
Speedread. Some people believe that speedreading causes you to miss vital information. The fact remains that efficient speedreading results in filtering out irrelevant information. If necessary, you can always read and re-read at slower speeds. Slow reading actually hinders the ability to absorb general ideas. (Although technical subjects often requirer slower reading.) If you’re reading online, you can try the free Spreeder Web-based application.
Use acronyms and other mnemonic devices. Mnemonics are essentially tricks for remembering information. Some tricks are so effective that proper application will let you recall loads of mundane information years later.
