Just finished my first semester doing BBA at Bath as well.
Enjoyed every week of my time being there, I worried too about it being boring (coming from busy Manchester to small Bath) but it really isn't as long as you make the most out of it that's available to you.
To sum up I've had such a good start I didn't go home for 11 weeks, now being at home I'm bored and craving to go back and I met some amazing new people.
