I found that my 1L group was helpful for doing practice exams and talking over them. Maybe you can find some people to do that with. I don't think study groups are neccessary to success, but I do think talking to other people can help you soldify your own understanding of concepts and hopefully they will bring up things you didn't think of and vice versa. That's especially helpful on issue spotting exams.I still study with one girl from my group last year because we have several classes together and she and I work very well together. I really like having only one other person, instead of a big group, because we stay on topic better.
