If you're nervous about taking your MCAT (or any other test) here bc of some of the negative reviews, IGNORE THEM. I was worrying myself for no reason over the some of the reviews I'd seen where people had bad experiences with the staff, but when I came the lady at the front desk was polite and everything went smoothly. Yes, they were kinda a stickler for making sure you follow their rules (read the sign on the door before coming in, use sanitizer frequently, etc.) but just follow them and you'll be fine. I guess it depends on who's working there that day, but you can have rude people at any location. Don't let that deter you from taking it here if this location is more convenient. Didn't experience any computer screens going black, power outages, or anything funky.
Also, come by before your test day to just check out the building! That really helped calm me down.
