What would you do in my position?

<p>I'm involved in a program where I attend a CC my senior year. Because of this, I wiped out a big portion of my lower division undergrad. I am looking to apply to Haas, but the Haas administrators have advised me to wait two years to increase my chances. </p>

<p>Does anyone have any recommendations as to what I can do for two years, class-wise? Do I just take a lot of breadth courses? Would it be ridiculous to retake prereqs? I was thinking about double majoring in Economics, but the very idea is pretty unnerving. Also, does anyone know if there is a possibility of taking Haas upper division courses even if I am not admitted into the school just yet?</p>
