American University transfer

Hey everyone! I'm Hayley, I'll be transferring from a community college this spring. I'll be majoring in accounting, and will be considering double majoring with the addition of finance. My current plan is to graduate with my BSA and work for a couple years hopefully with one of the Big 4. My goal is to transition into investment banking. I have already read a few forums on here about that route, in which a few suggested in transaction advisory services (due diligence). Past that point I don't know much. I am still fairly new to accounting. I actually just got into learning more about investment banking today, sounds very interesting to me. If any of you could expound upon that plan with advice I would be very grateful. In any case I look forward to learning a lot more from this site, and from all of you! Hope you all have a good Christmas.
