Module 2A-5: Activity 3: Spreadsheet for Administrative Purposes

Today I completed Activity 5 for this course.  Most of the material I was fairly comfortable with but I had some difficulties with the "COUNTIF" function.  I was asked to determine how many students got A's, Bs, etc but there was no criteria for the different ranges.  I can use nested IF's for this requirement but I would still need to know what is the cut off score for say a "B".
