While most of her college mates used lists and flashcards to memorize stuff, Van used a whiteboard to write out all her notes in the form of Starry Night, Van Gogh’s famous masterpiece. "I knew I had to study for this exam, and I knew I’d be writing on this whiteboard for hours," she said. "So I thought, ’ Wouldn’t it be funny if I did it in a form that people didn’t know how to feel about it?’ "
