Calculate Grades From Declared Course Rules

Calculate course grades from declared category weights, dropped assessments, exemptions, caps and missing-work rules using exact decimal arithmetic.

Features

• Drop the selected lowest assessment ratios and retain reasons for included or excluded work.
• Apply category and final percentage caps with explicit empty-category handling.
• Choose half-up, half-even or toward-zero rounding at the final output boundary.
• Save course grades, assessment calculations and category totals with exact intermediate values.
