AUTOEBALUATION

- the first point I think that we do it correctly, sometimes one person is not doing nothing but we say him that he start working.
- the second point I think that we don´t do it correctly, because some things we don´t do for the dead line and we try to do for the next class.
- in the third point we don´t put any objectives to do the works on a day, and I think that if we put one objective we can do all the works on a day.
- in point four, when we take an decission we have the similar ideas and opinions.
-in point five whne someone is doing another thing that is not a work we say that he must do the work.

In general I think that if we put some objectives we can work correctly and we can do a very well work.
