hello, all I need are the formulas for missing cells (E2,G2,H2,I2,J2)

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
