Medical Terminology Intuitive Section hot-anim This section was developed for 'speed learning' of medical terminology. Start by reviewing the meanings for a block of medical terms, and then go back and choose a previous term randomly and try to recall the meaning of that particular medical term before hovering over the term to determine the answer. These frequent mini-tests will accelerate the learning process and in a relatively short period of time, you will be able to quickly recall the meaning of all of the listed medical terms. This method of learning is superior to flash cards because of the frequent exposure and testing of your recall.
