you are going to be learning a lot of things in the coming months/years. it helps to have people to bounce these things off of and to discuss them with. it doesn't mean that you need to discount your own individualized study. however, with many of these subjects to come, it does help to have others to talk them over with and to hear their ideas about them. you can restrict your group activities to whatever will come to suit you. when i was in nursing school i belonged to a study group of 5 people. yes, we divided out the content and came together once a week where each of us was to be the "mini-expert" on one area of the content we had divided out among ourselves. however, we each also studied all the areas as well. there were times when we each failed to meet our "mini-expert" expectations and others in the group pulled us through the material. the group also help fill holes in our understanding and comprehension of any of the material. our group used to have a session before test brainstorming the kind of questions that we were likely to be asked. we had some sharp people who were were test savvy in my group that saved our butts more than once when it came to tests. that is the benefit of having a group. your group can work and do whatever you and your group members want it to do. you guys make the rules.
part of the problem of getting into a study group is choosing people who are similar in their study habits and learning to you. it takes some time to evaluate other students to find this information out. so, don't be too quick to jump into a study group of people you don't know. you may find some people desperate from the first day of classes looking for study partners. you have to ask yourself why they are doing that? so, keep your options loose and free. i wouldn't be too quick to commit myself to a group right off the bat until, perhaps, after the first big test to see where people start to fall with their grades.
i had a number of friends that were in medical school. they were all in study groups and did things a similar way. because of the massive amounts of knowledge they were responsible to learn they had to be more organized. they actually taped lectures and hired a secretarial service to transcribe the lectures and xerox copies of them for each of their members. now, you have to remember that these guys were a bit crazy about what they were doing and had the financial means to do this. and, it was not unusual that medical school study groups did this, i am told. how they do it today, i do not know. i can tell you, however, that it is tremendously hard to get through medical school without belonging to a study group.
professional educators will tell you that when you are learning new concepts it helps to be able to be exposed to it in many different ways. talking about it (as in groups), devising games and memory techniques as well as plain, outright reading of the material help you to comprehend the major ideas behind the words. and, this is the important goal of study. this is all important when it comes to critical thinking during tests when you are presented with those application questions that i'm sure you have read about on other posts, particularly the nclex style questions where you can know the knowledge, but if you fail in the critical thinking part of the question, the knowledge means nothing.
