UPGRADE Vocabulary, a test preparation app that offers 440 most frequently encountered words on the GRE and 150 practice test questions, utilizes newly revised testing formats and patent-pending, associative/multi-sensory learning techniques. By playing a virtual piano, individuals are given aural, visual and kinesthetic cues that enhance vocabulary acquisition and retention. To reinforce learning, individuals practice, rehearse, perform and engage in master class exercises. Special features of the app include self-selected audio and color preferences, word pronunciation, and a lexicon and reverse dictionary.
