The "Start Exam" button cannot only be clicked ONCE
The "Start Exam" button can only be clicked once. If it appears grayed out, it means it was already clicked previously and either your system did not meet the necessary requirements to take the exam, or you connected with a proctor and chose not to proceed.
To reactivate the option and review your situation, please contact our support team at support@aaafoodhandler.com for assistance.. Thank you.
