Once you turned 18 he could have stopped paying but apparently either doesn't know it or doesn't want to stop either way you should be on your mothers account if you are the only survivor in the event of her death.
If your name is on her account then that means nothing. My name is on my mother's account because when my father died she found out how hard it is to get the money from the bank(and we aren't talking about large amounts of money). Now if she was trying to hide your money in her account that would be a separate issue, but it still wouldn't make a difference.
When your father takes this to Court he will show you aren't enrolled or enrolling in school. That is what is going to really matter at your age.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
