Step 1: Add up all the scores from the student's assignments and tests. Step 2: Change the total scores for each part into a Percentage Score. Step 3: Convert these Percentage Scores into Weighted Scores, which show how important each part is in helping the student learn different subjects. Step 4: The total of these Weighted Scores for each part becomes the Initial Grade. Step 5: Write down the Quarterly Grade for each subject in the student's report. These steps make it clear how final grades and the overall average are calculated in the DepEd K-12 grading system, ensuring an easy understanding of student performance evaluation.
