Ellie is not sure of your solution to Problem 10.

Schedule and Appointments

My door is generally (not perpetually) open, and you are usually welcome to enter when it is. However, I ask that you try to keep to posted office hours, or make an appointment for an alternate time (email is generally best), whenever possible. Occasionally I will either be out of the office or otherwise unavailable; these will generally not be noted on the weekly schedule. Open space on the schedule does not imply availability; this is especially true during the summer months.

To make an appointment, consult my weekly meeting and teaching schedule and then email me a suggested time you would like to meet. (Note: This is a typical weekly schedule, so disregard the date.)
