That is not true at all. Semester by semester. The guarantor can withdraw at any semester. Your assumption they can't is bullshit. They can. They absolutely fucking can. They are only on the hook for the semesters they guaranteed for. I don't know where you live that this is different, but in canada and the u.s. you pay each semster, which means each loan is for a semester. The guarantor can refuse to guarantee future semesters and then you are on the hook yourself, and god forbid the bank decides your parents make too much money, they won't give you a fucking loan at that point and you are fucking screwed. Thay aren't on the hook for 4 years by guaranteeing 1 semester. That ain't how it works.
