Pay attention and do your homework and classwork completely. Don't use your phone and chat excessively. So far in CP Algebra 2, we have used the textbook and a few packets (-> from Algebra 1) for the first two units, but don't throw the packets away as they are helpful for studying for the summative. He doesn't check homework; don't skip them and make sure you understand everything. Take advantage when at the start of class he asks if there are any questions because he will thoroughly explain and solve the problem. Also, there are one or two check-ins (formative quizzes) he gives out per unit.
