It's crossed my mind. But, I thought I would think about an MBA after I got work experience-that is the main thing business schools care about.
Berkeley offers some Management, Finance and Accounting classes through Haas Business school over the summer, no admission required. So, there is that open if I don't want to pay $100k for an MBA. Classes are like $900 per, from a top3 school.
It looks like I could finish a B.S. in engineering within 3 years from today, i.e., 2 years after getting my B.A. As a CA resident living in university housing project, college has been $17k per year including food and everything. Beats the $56k my friend's Dad paid to send him to Columbia (*apples to apples)!
I feel moving up the ladder might be the eventual plan. But, I really do have some academic interests that I want to satiate before it's too hard to do. The reason I say this, the people I know that have graduated from undergrad business school are wankers, with few things to talk about other than how to get a $70k job fresh out of college doing accounting for 60 hours a week.
