Totally depends on the situation. I know some people that paid if off in as little as 3 years living very minimally and others that let is accumulate over 10+ years to make larger financial obligations (purchasing practices, homes, etc.). You need to weigh your options and take into account your goals.
Sounds like you’re already starting off with minimal debt and lower tuition; that’s is a HUGE plus! Pay down your interest, pay off your highest interest rate loans first. It’s only money lol
