August, 2013 Students: Please keep in mind that the averages reported on Parent Assist are never correct. If you try to calculate your final average, you most likely will get an average greater than the correct value. Consequently, while you may think your average is 84.7% and your grade would be a "B", in actuality your average could be 83.2%, which would be a "C".
