He has compiled a Grade Summary Sheet and started a Grade Inquiry Sheet. He needs you to complete the following tasks: Grade Summary Sheet: Task \#1 Complete the formula for the "Total Points" Column J. Task \#2 Complete the formula for the "Percentage" Column K (keeping in mind that you also need to complete the Points Earned at the bottom of the sheet). 2 decimal places please. Task \#3 Complete the "Grade" Column L so that a letter grade is populated in that column. Task \#4 Professor Warfield would also like for you to make a copy of the Grade Summary Sheet, prepare a summary of letter grades indicating how many " A 's", "A-'s" etc. there are in his classes.
