As stated on our site:
Extension are only given If you have a medical emergency, course extensions may be granted (no more than 2-weeks) at our discretion, but an official medical note must be provided along with request for extension. Please contact us at firstname.lastname@example.org along with supporting documentation.
Extensions/transfers/changes are not permitted for courses for any other reason. Course-work must be completed on-time, especially with NYC courses where course-work must be submitted before the semester end-date.
