You need to calculate final grades for the professor, using the following guidelines:

$1.$ This class uses weighting, which you will need to account for in the calculation. Exams are worth $80\%$ of the grade, and the class project is worth $20\%$ of the grade. To calculate the final grade percentage you will need to add up the exam scores; then divide by the total number of exam points and then multiply by the weighted percentage. In a similar manner, calculate the percentage for the project. Then add the two totals together to get the final grade. Remember, students cannot earn more than $100\%!!$

$2.$ Once you have the grade percentages, then calculate the letter grades and plus$/$minus letter grades.

$3.$ Next, complete the data for columns M through R showing the grade percentages $($Note$**$ do NOT use adjusted percentages!!$),$ the corresponding plus$/$minus letter that equates to$,$ how many students had that grade, what percentage that is of total students, the grade point and the average.

$4.$ Using the letter grades and total students $($columns N and O$),$ create a Grade Distribution graph.

$5.$ Use the technics you learned in the module to complete the file, then complete the assessment questions using the file you create.

How many students earned a B in the class? $($not B minus or B plus$)$
