What you need: Smartphone, a notes app

Risk level: Medium

When you think of cheating with technology, this, more than likely, is what comes to mind. Nothing fancy about this method: You gather the info you need for you exam and enter it into the notes app found on your phone. Every smartphone has a notes app—even the cheap ones you can get for free from Walmart. While taking the test, sneak your phone out and peep your notes without getting caught. Done and done.
