^ it’s water under the bridge since those apps were due in November. However, you have to shift your thinking quickly - you’re likely have loans until your mid 30’s, which means wasting $400 on something ‘just cause’ is no longer possible. You’ll be scrimping and saving every dime. You won’t be able to buy a new car, to choose where you live. You’ll have to share an apartment, drive a clunker, eschew going out. $400 is a lot of money that you could have used for books next year, for example. They’re $400 you’ll have to ‘earn back’ because you’ll need them.
I’m guessing your parents have a high income and have always spent lavishly, with no savings, so all of this will be new to you, and it can be really tough to adjust.
