For 2025, probably not. She must have actually attended classes full time (typically 12+ hour load) to be considered a full time student.
But, it may depend on the details. Why did she not graduate sooner; example: she was working on a thesis. If the school considered what she was doing as being enrolled as a fulltime student (unlikely), then maybe yes. Then it would depend on when in 2025 she graduated (it must have been May [even May 1] or later to meet the 5 month rule).
Scholarship money, including a Pell grant, that was received in 2025 and not spent on tuition, books or other course materials (e.g. it was used for living expenses) is taxable income to the student.
