⚠️ Common Concerns and Solutions
Online Testing Concerns

"What if the proctor can't hear/see me clearly?"
Solution: Proctor will work with you to adjust webcam angle, lighting, or audio before exam starts. System check occurs 10-15 minutes before exam time to resolve technical issues.
"Can the proctor see my entire room?"

Solution: Choose online proctored exam instead - available anywhere with internet. If you must test in-person, ESCO has 500+ locations nationwide. Search their locator for nearest center (may require 30-60 minute drive).
