In my opinion, I think students who work and study together is may got some negative effects. Most of the students work in part time, but what happens with their life school? Usually these people do not have time for doing their homework, or take extra classes or courses, neither for studying for their exams. If those students are responsible, they can do so in their free-time, or keeping awake at night. However, they need to take more time for their studies because it can affect their grades.
