Work alone or work in group? In my opinion, I prefer to work by myself. Doing homework alone means efficiency. Take an example of my own, last semester, my sociology teacher gave us a group work about introducing a topic and giving a presentation. It was due to the end of the month, but there are a lot of preparation works should be done and it took us a long time to schedule a time for each member. Also, I found there are some free-riders who literally did nothing but swiping there phone aside. So given the chance, I think I would rather finish the assignment by myself.
