The best thing about Bentley is its size. A lot of people (including myself) were afraid to attend a school that was too small. If it was too small, you would get bored too quickly, you'd meet just about everyone in the first year, it would feel like high school, etc. Bentley is roughly 4,000-5,000 undergrad. I don't feel like I have even come close to meeting half of the students in my class after 3 years. It is big enough to have a lot of fun at, yet small enough to get VERY individual attention, have small classes, and can provide resources for all of its students.
We also have a "trading room" that is unmatched by ANY school in the WORLD. Better than what can be seen at Harvard Business School, Wharton (at UPenn), MIT, Columbia Business School, or any "top-notch" business school in the country. We have all of the financial software and tools used at top financial institutions across the globe. When I showed up for my first day of work at Morgan Stanley I knew how to use their software better than 25-year industry veterans.
Following the theme of business technology, we also have the Center for Marketing Technology and the "ACELAB" (Accounting Center for Electronic Learning and Business, basically an accounting software room). There is no software you will be unfamiliar with after leaving Bentley. I can't truly comment on either of these as I am a finance major, and the experience I've had with both is limited at best.
