There’s another thread you should read about someone wanting to pull out of their ED decision to CMU because the financial aid wasn’t what they expected. Before you decide to go and switch to their version of “ED2” I would seriously consider what it would cost you, especially if you have never visited because it is TINY! It takes a certain kind of student to love CMU and it is definitely not for everyone. We loved it and my oldest loved it, but not my other 3 due to it’s size. My son even felt Wash U was too small and this is even smaller than that!
Additionally, they are skimpy on financial aid and their COA numbers alone are about $77k just for this year. That doesn’t even include travel, entertainment, extra food, miscellaenous, etc. I have a child at a school who’s COA is just slightly higher, and all I can tell you is that all in it is at least 5k more than that even. So expect for your parents to make it work, it will be more than $82k a year and probably more. The travel can really be a killer too. Also if they require their own health insurance plan as that’s sometimes not listed in the COA and then thrown at you that could be another few thousand.
You’re already in somewhere decent with money. You’re better off staying RD and maybe getting on a waitlist as opposed to being in a binding decision or only the admit/deny.
There are other CS programs with AI you can find if you wanted to. But if it’s a sacrifice to your parents, then definitely don’t do that to them.
