Alternate major?

<p>I am most likely applying to UCI as a biomedical engineering major with Mathematics as my alternate. I am assuming that biomedical engineering is a reach since i dont have like 2 of the major prereq courses completed. What are the chances that I will get in as a math major which is easier. Would having my main major be math give me a better chance of getting in? Like how much emphasis do they put on the alternate</p>
