Some times it can be really difficult to study alone. Even though your eyes are focused on the textbook, your thoughts wander, and it can be hard to retain information. One solution to this is studying with others, or in a group.
One important thing to consider when creating a study group is making sure you have one person that can keep everyone on track. Also, having too many people in a study group can disrupt coordination.
The main advantage of studying in a group is that you are aware of how much the other person is studying and at what pace. This factor acts as a positive motivator for keeping up with your own pace and drive to study.
