this is my second semester of nursing school and i still dont have a study group because of the same issues you raised.....you can do it on your own,just study really hard but if you have a problem just walk up to someone and ask them,i'm sure there one or two people in the class just like you. i dont worry about it anymore,i study hard and i do great.email you instructor about any questions you might have. when you start clinicals,you might make a feww friends from your group
