If I were to borrow money from my sister to pay $40k in tuition for my graduate program, how does that affect mine and my sister's tax situations?

My sister cannot claim me as a dependent. Can she deduct the borrowed money from her taxes?

I read in an article that in order to qualify the borrowed money as a "loan" I have to set up some sort of an interest system. Otherwise the borrowed money is seen as a gift and I have to pay taxes for that. 

Do I report the borrowed money as income?

Can I use my tuition paid as a deduction even though technically I borrowed money from my sister and will pay her back eventually?
