Sara Shared "Student Created: Polyposis Syndromes" - 4 Picmonics
With Picmonic, facts become pictures. We've taken what the science shows - image mnemonics work - but we've boosted the effectiveness by building and associating memorable characters, interesting audio stories, and built-in quizzing. Whether you're studying for your classes or getting ready for a big exam, we're here to help.
