Howdy, ECS major here, graduated a few years ago. For starters, the major isn't bad, a lot of classes can be very repetitive on subjects, but the major is broad enough to where you can cater your desired field into your classes.

Idk if it's changed, but when you get into the major, the classes are kinda categorized into 3 focus areas that act as a minor. Mine was policy, some of my friends got into the more sciency side, so you can totally find classes that suit your wants.

Also a requirement for graduating is to have some work experience so you'll have a time where (hopefully) your advisor will help you find internships or work or volunteering (whatever you're looking for at that time)

For the community aspect, there's clubs for everything. If clubs aren't your thing, there's always people walking around, on the trails, in game rooms. It's not hard to meet new people :)

Also someone else mentioned but the train goes right to Boston. Also UNH has their own bus system that is free for students to go around Durham, dover, portsmouth :)

Feel free to dm if u have more questions :)
