While BU certainly has its downfalls, most of which are due to the sheer size of the University, there are plenty of opportunities to take full advantage of all that it has to offer. For the resourceful and motivated, a little effort will go a long way. The most important thing is to utilize your professors to your advantage. It is their job to be available to their students, and while some are certainly more attentive than others, students are not turned away by a professor when they have gone looking for opportunities or support.
Keeping busy, being well-organized, and choosing a course of study that truly stimulates your intellectual interests will all be really helpful in having a successful experience at BU. Many students dread graduation day, and therefore, leaving Boston is not something they look forward to. On the flip-side, countless others would argue the opposite perspective. Accept your environment and work with it, as well as against it. Do not stay inside for too long, and do not drink away your college years. Make school a priority, and hang out with your professors (they are the best resource you have). Boston is a huge city with a really large population of young people. If you are looking for a taste of city life, and think that you would be able to establish yourself at a big university in a high-paced atmosphere, it is definitely possible to find your niche here.
