You will need to log in to your proctoring session 15 minutes prior to the scheduled start time of your exam.
Your proctored exam starts at the scheduled start time provided in the exam reminder email. Please note that you still have to complete the pre-exam steps with your proctor before you can proceed to your actual exam. Please make sure that your exam environment must be visible clearly on the webcam while taking the exam.
For more information on how to log-in to the Proctoring session, we highly recommend to visit How do I connect to the proctor to start my exam? and Proctoring Tool Manual
