If I’m applying to biomedical engineering, can I write my supplemental about why engineering as a whole instead of bioengineering in particular? My alternate major is also in engineering as well.
I’m just a parent, but I would say sure… why not. My son wrote his main common app essay on his area of interest, Chemistry, based on essay prompt #6 (“Describe a topic, idea, or concept you find so engaging that it makes you lose all track of time…”). He did not want to repeat himself in his WashU essay, so he focused on scientific research generally, with reference to a specific research project in which he was involved. Best of luck!
