For student it says it had to be for 5 months. Does that include time they were accepted. They were in the fall semester starting in September but accepted earlier year

Q. For student it says it had to be for 5 months. Does that include time they were accepted?

A. Yes.  More specifically, the technicality is "enrolled", not "accepted".  If the student was enrolled, in August, he meets the 5 month rule. 

If the student was in high school, earlier in the year, that also counts as being a Full time student.
