Memorization is another technique to use to help with studying. Several memorization strategies are suggested for studying.
One strategy is using acronyms. An acronym is a combination of letters that represent words that need to be remembered. An acrostic is a sentence or rhyme that has a first letter cue for you to remember. Many people use lists to memorize. You can also invent stories about each component of the list by using a strategy called chaining. Another memory technique is to put what you have to remember in a certain location and walk to it. Keywords are another good memorization tool. Another tool is to put an image with a keyword in an effort to remember it.
Two suggestions. Try Gingko Balboa and those Brain Age games for either the DS or Wii. Those two things seemed to greatly help my mom. You might be in a funk from lack of sleep.
