The reflective surface requirement is listed on their getting started guide (https://www.proctoru.com/howitworks.php) option 5 of their pre-exam checklist. It's designed to prevent people from putting notes on their computer monitor. I'm not sure about TESC's information / involvement as I have only taken SL courses so far. I have yet to take a TECEP. Hopefully you passed tho!
