On the other hand, being a part of a study group that requires you to compel yourself to attend after the class or during your rest days is one of the disadvantages of participating in such a group. The level of commitment displayed by each individual participant is an essential component of the study group. As a result, you and the other members of your group will need to forego participating in any other activities in order to study together.
And one more thing: if you and your other students are simply having a good time and forgetting about the material being studied during the study group, then that is another problem. It is the parents' responsibility to ensure that their children are studying in groups and are not having fun, giggling, or gossiping while doing their homework. A constant presence of parental guidance is required.
It is entirely up to you whether or not you want to sign up for a study group; there are some people who perform better academically when they work on their own. If you think that joining or making a group will help you learn more, then go ahead and take advantage of this fun way to learn.
