No, you can't claim education expenses for a deduction or credit unless you paid them, or took out loans to pay them. 

Maybe.  How old are you and how do you support yourself?

If you are a student, over age 23, and are not claimed as a dependent by someone else (e.g. your parent) you may be eligible for the up to $1000 refundable American Opportunity (tuition) Credit. That credit is not dependent on having either kids or earned income. You must be at least a half time undergraduate student. There's even a loop hole available to claim the credit, if you are on scholarship.
