A. Use breakpoints to enter the grading scale in the correct structure on the Documentation worksheet, and the name the grading scale range Grades. The grading scale is as follows:

95+ | A | 90-94.9 | A- | 87-89.9 | B+ | 83-86.9 | B | 80-82.9 | B- | 77-79.9 | C+ | 73-76.9 | C | 70-72.9 | C- | 67-69.9 | D+ | 63-66.9 | D | 60-62.9 | D- | 0-59.9 | F |

B. Calculate the total lab points earned for the first student in cell T8 in the Grades worksheet. The first student earned 93 lab points.
C. Calculate the average of the two midterm tests for the first student in cell W8. The student's average midterm test average is 87.
D. Calculate the assignment average for the first student in cell I8. The formula should drop the lowest score before calculating the average. Hint: You need to use the combination of the three functions: SUM, MIN, and COUNT. The first student’s assignment average is 94.2 after dropping the lowest assignment score.
E. Calculate the weighted total points based on the four category points (assignment average, lab points, midterm average, and final exam) and their respective weights (stored in the range B40:B43) in cell Y8. Use the relative and absolute cell references as needed in the formula. The first student’s total weighted score is 90.
F. Use the appropriate function to calculate the letter grade equivalent in cell Z8. Use the range name in the function. The first student’s letter grade is A-
G. Copy the formulas down their respective columns for the other students.
H. Name the passing score the threshold in cell B5 with the range name Passing. Display a message in the last grade book column based on the student’s semester performance. If a student earned a final score of 70 and higher, display Enroll n CS 202. Otherwise, display RETAKE CS 101.
I. Calculate the average, median, low, and high scores for each assignment, lab, test, category average, and total score. Display individual averages with no decimal

Melting Point Determination and Thermometer Calibration Lab Background: The melting point of a substance, a solid in this case, signifies the temperature at which the first crystal starts to melt until the temperature at which the last crystal disappears is reached. That being said, melting points are expressed in ranges, am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its…

That is because I have always thought that the idea of studying hard and exceling in school is the key for a good career in the future. Hence, the fact that the ones with bad grades are often the ones who…

rank or future plans. Classes are made up of groups of friends that pressure each other to disrupt the other students. Doing so takes the students attention away from what the teacher is saying and their work. If the classes were divided by grade point averages, the students that didn’t care would not be in a class with students who do care. Therefore they could learn better and be more prepared. Schools in today’s society are made up of the students who spend their time studying and students…

the freezing point depression of a known amount in an aqueous solution. Freezing point depression is a colligative property of solutions. There are three other properties, which are boiling point elevation, vapor pressure depression, and osmotic pressure. Colligative properties of a solution depend on the amount of solute and solvent molecules and not the specific properties of the molecules. The temperature at which the solvent starts to freeze will be specified as the freezing point of the solution…
