黑料不打烊

Hi, I want to cancel one of my Ap exam so I鈥檝e contacted my Ap coordinator but she said it is too late to cancel it as the date has expired. But when I look up in google, there鈥檚 one statement saying:

鈥淚n-person workshops: Registrants who cancel at least 21 days prior to the event receive a full refund. Those who cancel less than 21 days prior to the event receive a refund less $50.

Online workshops: Registrants who cancel at least 14 days prior to the event receive a full refund. Those who cancel less than 14 days prior to the event receive a refund less $30.鈥�

Then doesn鈥檛 this mean I still have time to cancel my exam? Or am I misunderstanding the context? Pls help me, this is stressing me so much鈥�
