I live in Phoenix, but as a distance education student working on an MBA, my exams must be proctored. For whatever strange alien reason, the Phoenix library system does NOT proctor exams! (Hello?!?)
Thankfully, the Mesa Public Libraries proctor exams. I've taken an exam each at the Main Branch and the Red Mountain Branch, which is this one. This one has dedicated rooms for proctoring (read: SILENCE!). The room was comfortable with a table and chairs, computers if needed, lots of natural light from a few windows, and in a back corner of the library away from the children's section. Dolores has been very helpful and responsive with setting appointment times and answering questions.
It is a drive for me from where I live, but I decided that's a good stress reliever pre- and post-exam...not as bad as it might be for others.
The library has free Wi-Fi and plenty of parking, though not a lot of covered parking.
