Studying in groups can be a helpful way to prepare for an exam. When you study with one or two other people in the class, you have access to the notes they have taken and things they recall about a group discussion. (Three heads are better than one!) Spend time quizzing each other on vocabulary terms or key concepts that you will need to know. You may even want to write up a sample test for each other to practice. And added bonus to group study is that breaktime can be a lot of fun!
