When taking these 7.5 hour practice tests, does anyone else get that pain in the shoulders/neck area and just feel the need to get up and move around? I used to get the same thing when writing lab reports for hours on end.
Correct me if I'm wrong, but I recall reading either in the Official Guide or the Prometric website that we may bring factory-sealed earplugs. Those would be far more comfortable than headphones.
Trust me, your USMLE exams will be just as long if not longer so this is good practice. This just underscores the need to practice multiple full lengths across your studies. You can build your way there by starting with half section tests, then to full sections, then to full lengths as you progress. Make sure you take your scheduled breaks as well to keep your muscles as relaxed as they can be. The MCAT is a marathon, not a sprint.
My recommendation is to definitely take each break even if its just to walk around to get your blood flowing and do some stretches. Don't power through and risk getting distracted by body aches. Also try to sit with your back straight and feet flat on the ground to avoid any cramps and remain focused.
My center was pretty noisy but thankfully they had a box of earplugs and offered everyone a pair. I was in my own world and didn't hear a thing. I would call your center and ask in advance because if they don't offer ear plugs you should be allowed to bring your own according to the official guide (as long as they're sealed). The plugs were great, top decibel rating and used in the air force, just make sure you use them right. You can buy your own if they don't have them. Amazon product
The over-ear headsets are painful and will numb your ears out after a while, at least my ears are sensitive to them. My only issue was that our chairs were terrible and wish there was more cushioning. Unfortunately you can't get your own chairs.
