None of the schools I’m applying to admit by major. I’m assuming they look at what you put down, since they ask, but once you get there you can declare whatever major you like ( I mean there are some exceptions such as BME at JHU, but nothing I’m considering in any case).
Also, I have done my research on JHU and the other colleges I’m applying to but I figure I didn’t need to spend a ton of time talking about why I want to go there for this thread.
