<p>If your mom doesn’t even want to go to the interview, that’s probably a hint that she doesn’t even want you going to the school. Even if you go by yourself, it will probably hurt your application because they might see your parents as not committed to you going to private school. If your mom’s made her mind up about this, there isn’t really much you can do about it. You could try to call the school and talk to them about your situation, but I don’t really know how that will help anything.</p>
