At a crossroad for my career choice

In 4 days I will begin my final semester with only 2 classes left to finish up my B.S. in Biology. I have had the idea of going to medical school, but probably over the past 6 months I have grown bored with it. I have always hated the biology degree, but figured since I was probably going to medical school I should just stick with it. I have always had a liking for stocks and the market. I first began investing when I was in high school and using whatever money I could scrape up from little paychecks to buy stocks. I have began to rethink my career path and thinking that someday I would be interested in running a fund. I know it is competitive and cut throat, but I am use to this as this is the same attitude needed to get into medical school these days. I am going to be graduating with a 3.8 gpa in biology in April, but what are the steps that I would need to take to switch over and look at getting my MBA? I have been looking into the Harvard 2 + 2 program since they specifically target non business majors who are looking to chance. What about getting work experience or an internship? I feel that my biology degree could possibly help me in the biotech sector for research or something. Any help the forum could lend me would be great. Thanks!
