Is the college an affordable one? Are finances a significant consideration?
If the college really doesn’t seem affordable to you, and you need financial aid for your kiddo to attend college, it might not be such a good idea to apply ED. With ED, if your kiddo is accepted, you will get that one financial aid package and net cost. You will have a short window of time to accept or decline the offer.
The thing is…that net cost could be the lowest, or it might be the highest. You will never know because all other applications must be withdrawn if you accept.
I can’t say whether ED is a bad or good idea for your student given the very limited amount of information in your post. But if you would benefit from getting financial aid…apply for it.
