Not Bad
Transportation to waltham is not bad, there are vans every 15-30 minutes until 2 am. There are shuttles to boston over the weekend including thursdays. there is the commuter rail as well, but it doesnt run often especially in the weekend.
parties are a lot over the weekend (Fri&Sat) especially during rush for greek life-- they are at off-campus houses. Student events and Student Activities and some clubs have big parties. International Club runs really good parties. There are Stein nights (restaurant/diner at school) with free food for all and free beer for 21+.
There are a couple bars in the area for 21+, no clubs except for Boston. There are students that have connections, they can arrange buses and get you on lists for clubs in Boston if you ask them. The bars in Waltham have Brandeis nights, Bentley nights etc. They are fun and chill.
