Group Project Marks

Today the teacher gave us a mark sheet so, we are supposed to evaluate the efficiency of our group. We were given 2 sheets to mark the group and to evaluate the group members. One sheet was to evaluate how efficient was your group. The first part of this sheets tells you to put checkmarks from 1-5 about the questions asked like how well did your group work to gether. The last 2 parts are talking about what made your group sucessful and what should the group do next time to do better. The second sheet was basically just a blank piece of lined paper, we are supposed to rate our group members from 1-10, and put comments on why you did you give this person the mark they got, and we are supposed to express our oppinion about if we should change our groups for the next project or not. In my oppinion no one should get a 0 if they atleast tried or put effort in to help, even very little it should atleast be a 1-2 not 0.
