Just for the sake of clarity, Cultural Enrichment extra credit is not applied until after the final exam has been taken.  It will not affect your pre-final exam semester average.  It will be applied in the form of a two percentage point increase on your final exam.  So an 88% (44 out of 50) becomes a 90% (45 out of 50) if you have done Cultural Enrichment extra credit.  This, paired with the modified grading scale, can make for a very significant increase in your overall semester grade.
