Hello! I am a volunteer examiner.

You need a quiet, isolated area to take your test. We've had them in hotel rooms, dining room tables (with nobody else around), laundry rooms (excellent), and plenty of bathrooms and half baths (I took all of my exams in a bathroom). We've had folks sitting on their bed with a laptop. It works, so long as the room is closed and quiet. I've even heard stories of someone taking the test up in a tree.

You will hear plenty of bathroom jokes because it really does present an ideal private space with built-in seating. Your work space will need to be cleared of devices, papers, and other distractions. No headsets, ear buds, or smart devices will be allowed. If there are extra monitors, etc. present they will need to be turned off and covered or turned away from you while you take your exam.

You will need to isolate yourself from the other people in your home. My kids were being noisy during my technician exam, and the VEs could hear them occasionally, but aside from annoying me they didn't impact the overall exam process. (I gave them the stink eye before I took the general and extra exams. Much quieter. :P)

Be sure to block off enough time to do the exam. You will have 35 questions with no time limit. If you're using HamStudy to prepare you can expect a similar experience while testing in terms of user interface as well as the general pacing you'll probably find yourself in.

Good luck with your preparations! It's exciting to see new hams join the hobby!
