Right now my dad buys our family’s health insurance through his employer and we are covered until age 25?

whether or not I am in school. My mom applied at a place where if she gets the job I would have health insurance until the age of 24 if I am a full-time student. What happens if she gets the job in between semesters? Which policy would apply? Serious answers only please.

your fathers insurance covers you until you're 25 period. unless he drops you on his insurance.
