The tutorials that I have attended were really pleasant, informal and had a relaxed atmosphere. Everyone has their own difficulty whether it be family, work, or social-based. The information shows that those who attend tutorials tend to do better, so it's worth making the sensory effort as well as the physical effort to attend. If anything at all, meeting your tutors once in a while helps keep the whole process in check, and will make it easier for you to contact them if you ever have any concerns (perhaps a difficult deadline).
I would try and make it to the first tutorial, and make your mind up from there. You can leave at any time, of course, although probably better to wait until the mid-session break!
