Absolutely true...group study is essential for students...back when i was in high school a teacher of mine gave us a group assignment. We were grouped according to our numbers on the class register. I wasn't friends with everyone in class but the group assignment helped me socialize. We researched together, chatted, became friends, and some of us even created a group study and it really helped us improve academically.
