In-Depth M.B.A. Explanations Needed

<p>I need a few people to explain to me in depth how getting an education works. My high school grades aren't the best, but I had a few counselors tell me that universities only look at the grades from your last 60 units. At the moment I'm a senior in high school, but I'm not sure what path I should take when I graduate. This is the way I picture it, but a lot of people are seeing a lot of flaws in it without telling me what's wrong. After I graduate from high school, I plan on enrolling into a community college for 60 units. Over there I will take a foreign language, all the needed general education, and whatever else I need. I will do my best. I look at it as a fresh start since my high school grades will never be brought up. Let's say I get all A's, and transfer to a university. Over there I will take their business administration courses. I want to get an M.B.A. Will I need to take all the math courses that lead up to calculus in community college or in a university when I'll be taking business administration classes? My number one choice for a university would be Berkeley. How would my chances of getting in be if I have a constant 4.0 G.P.A. as soon as I start taking my first class in community college? How about transferring to Berkeley STRAIGHT out of community college? How is an M.B.A. overall even? Is it a good major? Can I become an accountant for example as a backup plan with an M.B.A.? I would like to eventually be making 150k+. Maybe doing something along the lines of heavy management, analyzing, providing consultation, marketing, etc.. I know that you can choose concentrations when getting an M.B.A. Which one should I choose? M.B.A. with a concentration in finance, economics, accounting, management, marketing, etc..?</p>
