In my opinion, I prefer to study with a group of students. Because if we study alone, maybe we have something we don't know, for example you have a lot of exercises and tomorrow you have to submit. And you also have to help your mom to do the housework. If you study with a group, you will be faster than be alone. And maybe there are 2 more answer you don't know, so work with a group is better.
