　　Different people may find that different learning methods work best for them．While some would turn to tutoring in order to get better grades，others choose to join study groups．In fact，many universities encourage their students to form study groups and make good use of them．

　　"Two heads are better than one．"That's the simple idea behind study groups．By participating in a study group，students can benefit from some of their best academic resources：other students．They get to pick each other's brains and improve their own understanding of different problems．Moreover，study groups can create the slightly tense atmosphere in which it's good to study．For example，some students tend to procrastinate （拖延） when they are studying by themselves； however，by joining a study group，they get to observe their peers who are working diligently and are likely to thus have motivation for working harder．

　　Study groups work best when they are small，but not too small-four to five participants is about right．And it's necessary to make sure everyone has the same goal，to prepare for a particular test，to discuss class readings or to review the week's lecture notes．Besides，socializing in the group would make studying more fun as long as it took up only a small portion of group study time．

　　In addition，to maximize the efficiency，some study groups like to assign members certain roles，and thus efficiency will be promoted．Besides an organizer，who gets group members to agree to a common purpose and a convenient time and place，there often is a group member playing the role of a source-seeker，whose duty is to remind group members to identify their sources．For instance，when a group member says"I read somewhere that…，"the source-seeker should ask for specifics．This person reminds the group that it's important to know who said what and where it was said．And a gatekeeper，who tries to make sure that all group members are participating，may ask a direct question t
