What you put into school is what you get in return.  The grade you earn is the grade you will receive.  If you don't make the time to do it right, make the time to do it over....and for less credit.  Be responsible, be respectful and be truthful.  Do your own work, your fair share of group work , and take turns.  Don't lie, don't cheat, don't steal.  Clean up after yourself.  It's your grade, take an interest.  Science, it's a way of life.
