1. Running into an ex-coworker who I realize I'd rather be studying for an economy exam than talking to.
  2. Adding ten extra pieces of lead to my mechanical pencil in case I run out while filling out 40 multiple choice questions.
  3. Worrying the light is too dim to power the boyfriend's 20 year old solar power calculator. And moving it around in random patterns to try to get more light.
  4. Realizing I have no idea how to multiply fractions.
  5. Worrying the entire test is going to revolve around multiplying fractions.
