Not all diploma questions are still used. If you did not see it in class you do not need to know it. An example would be heating curves and acid-base stoich. Those are on the old diplomas but not in the new curriculum. They no longer ask questions about energy types in the provinces and Acid-Base stoich. Sorry things are in here a few times and I cannot add new ones.....gotta figure that out
HERE is a link to more diploma Q and A
