This was helpful but you had to flesh out the path and pharm. It was a great physiology review. I pretty much used my breaks for bathroom stops and then saved some time up for a longer lunch. I would definitely suggest bringing some ibuprofen or similar drug of choice because it's easy to get a headache from staring at the computer screen all day. There were a few teachers in the room recertifying for something who were too loud, but with earplugs it wasn't much of a problem.
Workstations are reasonably comfortable.
Fortunately, there is a restaurant and bar nearby for breaks. Otherwise, bring plenty of food and caffeine. Worry less about last minute cramming and more about getting a good night's rest before the exam. The only complaint I had was that the center was noisy, even with earplugs. I was at the test station right next to the door so it was difficult not to be distracted when people came and went.
