@rainyleaf What did you decide to do? If you have very sold math preparation, you can do the work at CMU.
If you got into SCS you can probably transfer to Dietrich College of Humanities and Social Sciences. The Statistics program looks very strong to me, and yes, thats a path if you don’t like SCS but you need to transfer-
Here are the rules about transferring into Dietrich.
