BME admission is a separate process so checking that box does not make your chance of admission into the university lower. However, the school does accept more BMEs proportionally during ED so be prepared to commit if you get in for it. I applied thinking I’d get into the school but not BME as well although I actually wanted to get in. If you get in it’s a win win situation (only if you can afford it though) since it is a phenomenal program and you won’t have to worry about other admissions, and if you don’t you’re not binded but may have gotten into the university as well.
