Returning to Undergrad for IB

<p>I'll try to explain a somewhat complicated system in as simple language as I can muster: I am about to start my senior year at Arizona State, which I attend on a National Merit scholarship...I am a Classics major, and have pursued the humanities and pre-med reqs pretty much exclusively through my undergrad. Now, I know this is a leap, but I have spent the last year struggling with a decision to keep doing what I am now or switching to finance/accounting (my papa is an accountant so I'm not going into that on a complete whim). I am planning to graduate from ASU in December, and I was planning on applying to law school for the following year and taking out loans. However, I have recently thought about applying to a target school for IB's, going back to get another undergrad degree immediately after getting my classics degree, and going from there. Has anyone heard of anyone doing something like that? I need to do some research on the application process etc, but the way I figure it, I would need to take out loans for law school anyway, so might as well bite the bullet and do what I'm actually interested, even if it is about 3 years late ha. This is pretty long, here is a quick run down of stats:</p>

<p>Major: Classics
GPA: 4.0
SATs (old): 1470
I tutor in the Honors College Writing Center and Latin
I teach a small group of high school students a private latin class in the evening
Working in a law firm this summer
Tutored at a public middle school on days that I did not have class last year
Worked at a golf course and as a bartender in summers past</p>

<p>So in short, have you ever heard of someone finishing their undergrad and switching to a different school immediately to pursue something totally different? Also, and idea what kind of a shot I would have at top tier undergrad business programs and target schools? Any advice would really be appreciated, and again, sorry to ramble on.</p>
