EXP ECH02 H4 - Professor's Grade Book 2.3
Project Description:
You are a teaching assistant for Dr. Denise Gerber, who teaches an introductory C#
programming class at your college. One of your routine tasks is to enter assignment and test
grades into the grade book. Now that the semester is almost over, you need to create
formulas to calculate category averages, the overall weighted average, and the letter grade
for each student. In addition, Dr. Gerber wants to see general statistics, such as average,
median, low, and high for each graded assignment and test, as well as category averages
and total averages. Furthermore, you need to create the grading scale on the documentation
worksheet and use it to display the appropriate letter grade for each student.
Instructions:
For the purpose of grading the project you are required to perform the following tasks:
Step Instructions Points
Possible

1 Start Excel. Download and open the file
0.000
​ named​exploring_e02_grader_h4.xlsx.
2 In the range A7:B9 in the Documentation sheet, enter
3.000
the breakpoints for the C grades. In row 7, enter ​70 ​as
the breakpoint for ​C-​; in row 8, enter ​73 ​as the
breakpoint for ​C​; and in row 9, enter ​77 ​as the
breakpoint for ​C+​.
3 Assign the name ​Grades​ to the range A3:B14 in the
4.000
Documentation sheet.
4 In cell R3 of the Grades sheet, calculate the total lab
9.000
points earned for the first student in the Grades
worksheet. Lab assignments are indicated by the
column labels L1 through L10. Copy the function to the
range R4:R21.
5 In cell U3 of the Grades sheet, calculate the average of
9.000
the two midterm tests for the first student. Midterm tests

are indicated by the column labels M1 and M2. Copy the
function to the range U4:U21.
6 In cell G3 of the Grades sheet, calculate the assignment
9.000
average for the first student. Assignments are indicated
by the column labels A1 through A5. The formula should
drop the lowest score before calculating the average
using a combination of SUM, MIN, and COUNT. The
argument for each function for the first student is B3:F3.
Find the total points (SUM) and subtract the lowest
score (MIN) from the result. Then divide the remaining
points by the number of assignments (COUNT) minus 1.
Copy the formula to the range G4:G21.
7 In cell W3 of the Grades sheet, calculate the weighted
6.000
total points based on the four category points
(assignment average, lab points, midterm average, and
final exam, in that order) and their respective weights
(stored in the range B30:B33). Use relative and absolute

cell references as needed in the formula. Copy the
formula to the range W4:W21.
8 In cell X3 of the Grades sheet, use a VLOOKUP
9.000
function to calculate the letter grade equivalent. Use the
range name to reference the lookup table in the
function. Copy the formula to the range X4:X21.
9 Name the passing score threshold in cell B1 with the
4.000
range name ​Passing​.
10 In cell Y3, use an IF function to display a message
6.000
based on the student’s semester performance. If a
student earned a final score of 70 or higher, display the
label ​Enroll in CS 202​. Otherwise, display the label
RETAKE CS 101​. Use the range name in the function

(​Passing​)to reference the cell containing 70. Copy the
function to the range Y4:Y21.
11 In cell B24, enter a function to calculate the average
6.000
score for the Assignment 1 values stored in the range
B3:B21. Copy the function to the range C24:W24.
12 In cell B25, enter a function to calculate the median
6.000
score for the Assignment 1 values stored in the range
B3:B21. Copy the function to the range C25:W25.
13 In cell B26, enter a function to display the low score for
6.000
the Assignment 1 values stored in the range B3:B21.
Copy the function to the range C26:W26.
14 In cell B27, enter a function to display the highest score
6.000
for the Assignment 1 values stored in the range B3:B21.
Copy the function to the range C27:W27.

15 In cell Z3, insert the RANK function to display the first
6.000
student’s rank in the class based on the student’s total
points compared to the range of all students’ total
points. Copy the function to the range Z4:Z21.
16 Insert a list of range names starting in cell D3 in the
5.000
Documentation worksheet.
17 Create a footer on each worksheet with the text
6.000
Exploring Series​ on the left side, the sheet name code
in the center, and the file name code on the right side.
18 Ensure that the worksheets are placed in the following
0.000
order in the workbook: ​Documentation, Grades. Save
the workbook. Close the workbook and then exit Excel.
Submit the workbook as directed.
