SlatePermutate can be a useful tool for scheduling your next semester at Cedarville University.

  1. Get in touch with your advisor during advising/reading recess.
  2. Look up each class your advisor specified on this course listing page
  3. Enter each class into a SlatePermutate schedule and add each section that is listed that you are willing to take.
  4. Submit your schedule and view all of the different permutations of your schedule which would work with the sections you specified.
  5. Print out your preferred schedule by choosing "print" and selecting a schedule.
  6. Wait until it's your turn to register and grab your preferred sections before they fill up!
