Yale does not have ED but Single Choice Early Action (SCEA). If you are extremely low income (less than $60,000) your tuition, room, board, fees and some expenses will be covered in its entirety. You will probably also be eligible for a fee waiver for your application. So, if you want to apply, go for it. With SCEA, you do not have to give your answer until May 1 like the other schools and you can therefore look at other packages. But since Yale will probably be no cost to you, if you were to get accepted, it may be a viable option. One last piece of advice - Yale is a great school, but it is not a dream for anyone. It is a real place in the real world. It was good for me and good for my daughter, but it is not the right place for everyone. Please look at all aspects of it closely before making any decisions. You have to LIVE there for 4 years.
