Ch 10Ch 9Ch 8Remember that your Test score is one third the 1st test and two third the retest.Formula: [ (percent you want) - (1st test percent) ] * 1.5 + (1st test percent)Example: Your 1st test is 84% and you want a 90%.[ 90 - 84 ] * 1.5 + 84 = 93%So you need to get a 93% on your retest to average 90%.The most common question I hear at this time of the year is . . . "What do I need on the Final to get an A?"
