studying phase

  1. Make any ability check you want against the exam's DC. Success = 1 reroll
  2. Pulling an All-Nighter: automatic 2 re-rolls at the cost of 1 level of exhaustion (disadvantage on all ability checks)
  3. Studying together: gain advantage on your studying phase ability check
  4. Skip: you can skip studying and forgo any chance of earning rerolls

testing phase

You make two ability checks, determined by the exam, with a DC also determined by the exam.
