Empowering IGCSE Students Worldwide

Welcome to the IGCSE Grade Calculator. We are a specialized educational platform designed to provide clarity, precision, and ease for students, teachers, and parents navigating the rigorous landscape of International General Certificate of Secondary Education (IGCSE) examinations.

Our Mission: To eliminate the need for students to calculate their grade based on complex formula, we have created this tool that easily calculate your weighted marks and grade based on previous grading thresholds.

The Challenge of IGCSE Grading

Calculating a final IGCSE grade is notoriously complex. Unlike standard school tests where $70/100$ might simply be a 'B', Cambridge International (CAIE) and other exam boards use a sophisticated system of Component Weighting and Curved Thresholds.

For instance, in Biology (0610), your Multiple Choice paper, Theory paper, and Practical paper each carry a different percentage of the final mark. Furthermore, these marks are adjusted based on the difficulty of the specific exam series (e.g., June vs. November). Manual calculation requires digging through 40-page PDF documents—a task that is both time-consuming and prone to human error.

How Our Calculator Works

Our platform automates this entire process. We maintain a comprehensive database of the latest Grade Thresholds (currently focused on the November 2025 series) and apply the exact weighting factors specified in the official subject syllabuses.

Official Thresholds

We sync our data with officially released grade boundaries from CAIE(2025 November) to ensure the highest possible estimation accuracy.

Weighted Calculations

Our algorithm handles the math for Paper 2, 4, and 6 (or other combinations) according to the official weighting guidelines.

Multi-Subject Support

From Mathematics (0580) to Art & Design (0400), we cover a vast range of subjects and variants (over 50+ subjects).

Instant Results

No registration, no emails — just enter your raw marks and get your predicted A*-G grade in seconds.

Why Trust Us?

We are a team of educators and tech-focused learners who have "been there." We understand the pressure of the IGCSE years. Every line of code in this calculator is written with a student-first mindset. While we are an independent entity and not officially affiliated with Cambridge University Press & Assessment, we treat their data with the utmost respect and diligence.

Commitment to Improvement

Education is dynamic, and so are we. We are looking forward to update our tool to include:

The latest 2026 examination variants.
New subjects added to the IGCSE curriculum.
Mobile-responsive updates for students calculating on the go.
