PMP Study Aids: Does PMP Certification require memorization? PMP and CAPM aspirants use mnemonics heavily to memorize everything from Process Groups to Knowledge Areas, Process Names to ITTO's, and much more. According to Dictionary.com, Mnemonics are something intended to assist the memory, as a verse or formula. Most of us have used mnemonics in some form or another, for exams, work, or other purposes. I still remember the mnemonic - B B Roy of Great Britain has a Very Good Wife - that I learned during my engineering degree program more than 15 years ago. It was used to recall color code sequence for resistors. And who doesn't remember the acronym (a form of mnemonic) VIBGYOR for the seven colors of the rainbow.
