If you are a college student and on your parents insurance If you withdraw from a class and it puts you at under full time status 12 credit hours for the semester am you still covered on your parents?

Maybe. :) It depends on the insurance policy, actually. It depends also on how old you are, and why the insurance is covering you. Some policies are written to only cover full-time students, but most policies that you don't buy through the school will cover you anyway. Hopefully you are still covered, but the only way to know for sure is to ask your parents' insurance agent.
