For engineers interested in having impact through the market, MIT has many resources.
MIT students can take any other MIT course--including management courses in Course 15 (Sloan School of Management). You may learn about anything from finance to patent law to organizational management. Taking Sloan courses is also a great way to meet business partners to enter MIT's $100K Entrepreneurship Competition. It is also a great way to fulfill a minor requirement. Plan ahead: there is a bidding process for courses in high demand. First round building for next semester opens this upcoming September 27.
