Check the public exam listings at https://hamstudy.org/sessions and sign up for any available sessions that work for you. Note that a very limited number of VECs and VE Teams are currently offering fully-remote exams, but any of them that are using ExamTools should be listed as a hamstudy.org session. It is very important to read the special instructions provided within the session information prior to signing up, as additional scheduling steps may be required by the VE Team administering that specific session.
