Yea that was a fun area. My wife went to Northeastern and lived farther down Huntington in Jamaica Plain. Pretty sketchy area, but was pretty convenient for getting around town.
Honestly, grad school is about a thousand times easier than undergrad and the hardest thing is getting in. Maybe it's just that I'm 30 and not 21, but I haven't really been overworked. This is my second time through grad school and both times were equally easy. I remember putting in a lot of effort to get a 2.5 GPA in college, but I graduated with a 3.75 when I finished my Masters in Engineering Management and I've got a 3.75 now with only 4 courses left for the Engineer's Degree.
Undergrad placed a lot more emphasis on learning the fundamentals. Grad school is about expanding on what you already know. The bad thing is though that if you don't have the foundations down, they don't wait around for you to get it. There were a few times for some of my Fluids classes I had to meet with profs, but it ultimately came down to me learning it on my own, verifying what I figured out with my prof, getting the thumbs up, and moving along my merry way. Putting in effort in undergrad will pay dividends even if you don't see the material again for 10 or more years.
