Yes, I know that the money will be the one left over they take the part for all the tuition, fees and other charges.
That's right. The same way they will provide you all the supplies you need in time, so you don't have to worry to start the course without the things you need.
Another question I have, how do you decide which student loans to accept? I do not want to choose an aid that is difficult to understand
Contact the school and make sure you understand what you're accepting.
