Just for anyone else interested.
My MCAT was Sept 2017 at the Prometric Testing Center in Glendale, CA.
They gave us a colored booklet (2 pages of paper) and 2 pencils. We were instructed that while we could get as many new booklets as we needed, however we would have to turn in our previous booklet to get a new one. I asked why and there was once an issue of takers taking multiple booklets and using them to cheat via the restroom wastebasket.
If you bring your own earplugs, you can bring as many as you like, along with as many of their tissues as you want. I brought 3 pairs because I have a tendency to fumble them, and wrapped them in their tissues.
