The extra-curricular facet of the AIM application asks for the phone number of one's coach/adviser for each activity. What do we do if the phone number of a certain coach is through the school, via the school's phone number with an extension. I've tried to put the number in the standard format [(xxx) xxx-xxxx] and then add the extension, but it gets rejected every time. Is it okay to simply input the school phone number? Thanks in advance for any help!
