Brain is the most complex and powerful human organ, however researcher findings repeatedly stated that most people could not fully utilise the maximum 100 percent of our brain function. Memorisation of substantial information greatly relates to knowledge and intelligence. Human ability to retain and recall huge volume of information at rapid speed is never a myth. Right brain is capable of bulk image visualisation especially in fast speed. Developing photographic memory with rapid flash cards is the most effective mnemonics for right brain.
