#### Formulas Used

Section Score (%):

Score (%) = (Correct Answers ÷ Total Questions) × 100

Composite Score (%):

Composite (%) = (Sum of All Correct Answers ÷ Sum of All Total Questions) × 100

Minimum Correct Answers to Pass a Section:

Min Correct = ⌈0.70 × Total Questions⌉  (ceiling function — rounds up to nearest whole number)

For a standard 25-question section: ⌈0.70 × 25⌉ = ⌈17.5⌉ = 18 correct answers required.
