PREPARING FOR YOUR FINAL EXAM
*Please use your in-class review time wisely and study at home over a period of days –
this will produce better results than last minute cramming!
*Please ask questions or arrange a time for extra help if you are having problems, but I
will not just give you answers because you are too lazy to look them up or they are
missing from your notes – YOU are responsible for material you have missed.
*The best practice for calculation problems and naming/formulas for chemical
compounds is to go back in your notes and REDO the numerous questions provided.
Just “reading” through calculations or naming problems will not help you learn how to
actually do them/name them. Extra practice problems can be provided if requested.
