Study alone or in group

Topic: Some students prefer to study alone. Others prefer to study with a group of students. Which do you prefer? Use specific reasons and examples to support your answer. Firstly, I think one of the most valuable benefits of studying with a group of students is its efficiency. My friends may have better knowledge than me in certain fields. For instance, some part of the textbook that seems completely confusing to me could be quite clear to another student. Therefore, by exchanging knowledge and ideas with other people in the group I can easily find the best solution to reach the goal. In a study group, I can learn quicky by simply asking a question.It will require less time to accomplish the task.
Secondly, Studying with a group of students can help me to avoid mistakes. When I study alone, sometimes I am not aware of my mistakes and continue with them. On the contrary, by studying with a group of students, I can clarify unclear points with other students and someone can point out my mistakes . In this way I can avoid my mistakes in exam and enhance possibility of scoring good marks.
Finally, I believe that through study group, I can develop communication skills which are very important in modern society.In order to achieve the results, all group must exchange ideas in the forms of meetings and discussions. When I study with a group of students I cannot do my work properly without interacting with my friends. These interactions can help me to improve my communication skill .
