Hello johnson5,
You will need to call into Student CARE for an extension at 1 (888) 427-1000. Student CARE is available Monday through Friday from 9:00 AM until 6:00 PM, Eastern Standard Time.
Keep in mind that you are only allowed 2 total for the life of the program that you are enrolled in. Meaning that if it's a college level program, for example an Associates Degree, there are 4 semesters. You are allowed only 2 for all 4 semesters. You want to try to use them strategically.
A Student CARE Rep will be able to help. Best of luck with your studies!
