Thank you for the clarification.
This is one of those cases where "the spirit of what the IRS may have intended" is different from the literal wording.
I still think if you follow the wording of the requirement for Full time student, it could be interpretted that she is enrolled in January, attending classes Feb-May, so meets the 5 month rule. Someone could get all "F"s because they were asleep in cIass or even "skipped" all their classes but still be considered a full time student, but would that be within the "Spirit of the Intention"?
I would rather play it conservatively and unless I get evidence to the contrary agree with your interpretation.
