I am going to usc next year for architecture but am unsure about it. I am thinking about doing pre health instead. In Highschool, my application was more angled towards architecture but I did take AP Bio and flunked it in the first half but once I learned how to study properly I ended up acing the class in the second quarter. School didn't teach to the AP curriculum and I took it anyway and got a 3.

If I realize architecture is not for me, how should I approach prehealth? How does this work at usc? Sorry if this is a really dumb question. Can I just apply to switch when I get there? and what if i decide after a year architecture is not for me and I then want to switch?

Thanks! Fight On!
