This briefing document provides a comprehensive breakdown of the grade thresholds for the June and November 2025 O Level examination series. These thresholds represent the minimum raw marks required to achieve a specific grade (A* through E) in each subject. This data is a vital resource for O Level students appearing in the May/June 2026 exams, as it serves as a benchmark for evaluating performance on past papers and understanding the scoring requirements for various components.
Overview of Grade Calculation
To calculate a grade using this data, students must first determine the “Maximum weighted mark” for their specific subject and option code. The marks provided in the tables below are the minimum requirements for each grade after weighting has been applied. Comparing personal scores from 2025 past papers against these boundaries allows students to gauge their current academic standing and identify areas for improvement in preparation for the 2026 series.
Mathematics
Mathematics thresholds are categorized by the maximum weighted marks, typically 200 for extended options and 160 for others.

In conclusion, understanding the 2025 O Level grade boundaries is one of the smartest ways to take control of your preparation for the May/June 2026 exams. By using these official thresholds, students can accurately calculate their grades at home using past paper scores, rather than relying on guesswork. Simply total your marks, apply the correct weighting for your subject and option code, and compare your score with the grade boundaries provided above. This allows you to identify whether you are currently performing at an A*, A, or lower—and more importantly, how many marks you need to improve. Regularly tracking your performance using these grade thresholds not only builds exam confidence but also helps you focus on weak areas strategically. If used consistently, this method can turn past paper practice into a powerful, data-driven revision tool that maximizes your chances of achieving top grades in your O Level exams.
