Generally yes - but as we all know, many NPCs don’t calculate properly or many students input the wrong data and disaster happens.
Again, one can break ED but the question is - is it right to break a binding contract.
Obviously I disagree with the OP and what you are saying - but again, you can read countless stories on the CC and more of people who were misled or flat out erred in determining their aid.
All I’m saying. The schools all want you to apply ED - it’s in their best interest. In general, it’s not in the student’s best interest if money is an issue.
