The student’s grade in each of the subject area is determined by the combined results of her examinations and class work. The quarterly examinations make up 30% of the final grade and the class standing (comprised of quizzes, long tests, journals, and laboratory reports) accounts for 70% for the first 3 grading periods. For the 4th quarter, the final examination is given a weight of 40% and 60% goes to the class standing.

The grade is computed using the formula: T/2 + 50. This is based on the rationale that part of the student‘s grade is 50% of what she has learned in the previous quarters or lower years. The highest mark a student can attain is 99 and the lowest mark is 68.
