I am a freshman and already have credit for MAC2311, MAC2313, MAC2313, PHY2048, BSC2010, and their labs. Can I apply to upper-division BME in my first semester? 

No, we do not accept applications from freshmen to the upper-division BME major. Please consult with your advisor in 204 Weil Hall if you are a freshman and want to discuss applying to the upper-division BME major in your sophomore year.
