Ok, I was somewhat interested in finance when I was in high school, and I went to a community college and found the business classes very boring, so I started taking math and science classes, which I liked. I took up to Calculus 2, and some programming classes, and engineering physics I, and II. I was planning on transfering to an instate University that offered a program called "Applied computational and mathematical sciences" because this was where my interests were, in applied math, and especially computer simulations, which is exactly what the program was about, and it was highly regarded. I didnt get into the University though, either the first or second time I applied, and by that time I had become disenchanted with the idea aswell, and decided when I got into the other state university that I should major in Finance, because this university didn't offer a degree like that, and if I majored in pure math it wouldn't be exactly what I wanted and as a average math major I would have few job oppurtunities, but with less effort I could be a top finance major and probably have lots of job oppurtunities. Now I am a senior finance major, and so far I haven't been finding it very interesting, partially because most of the stuff is easy, and partly because I did a large research paper on the efficient market hypothesis, which is kind of a cornerstone of finance, and found it to be full of holes. Also, even for simple stuff like bond valuation, the methods they teach are actually incorrect and I asked a professor about this, and he said it was "a good observation" but that it was just the convetional way of doing it, even though it doesnt take into account compouding for interest less than a year. I have heard that you can go to grad school for things that arent related to your major, and I am wondering, is this really true? Could I really be accepted into say an applied math, or biology or engineering grad program, striaght, or would I have to redo my undergrad and get a second degree?
