What are grade boundaries?
Grade boundaries are the minimum raw marks Cambridge requires for each letter grade on each component of 4037 Additional Mathematics. They are not fixed percentages — your overall O-Level grade uses a weighted aggregate across the papers you entered, and each paper variant has its own row in the official PDF. Match your exact component codes from the statement of entry before comparing marks to any past session.
How Cambridge sets 4037 boundaries
For Cambridge syllabus 4037, cambridge sets 4037 thresholds after all scripts are marked so each grade means the same standard every year. Calculus and coordinate geometry chains need every differentiation/integration step shown for method credit. When a paper is harder than the previous June series, raw cut-offs usually fall — comparable outcomes, not fixed quotas. Compare only to verified 4037 sessions ([wrong-session estimates](/insights)).
