IGCSE Grade Calculator
This tool provides an estimate based on your entered marks and the November 2025 Series grade thresholds. Your actual exam results may vary depending on the specific boundaries set by the exam board for your session. These predicted grades are for reference only and do not guarantee final performance. While we strive for accuracy, grade boundaries are updated periodically. We recommend cross-checking with the latest official board publications as we could not ensure 100% accuracy.
About IGCSE Grade Calculation
This tool calculates your final IGCSE grade by multiplying each component mark by its weighting factor and summing these results to get a weighted total, then comparing this to the official November 2025 grading thresholds released by CAIE. Whether you are taking CAIE IGCSE Biology (0610) or Mathematics (0580), understanding your weighted score is crucial. We save you time—no need to search through thousands of subjects to find your grading thresholds.
How to find my component marks?
You can find your raw marks on your result slip or by asking your school coordinator for the component marks report.
Does this thresholds reflect the latest IGCSE exams?
No, it is currently based on the Cambridge International (CAIE) 2025 November series grading thresholds. We will update this as soon as possible.Most of the time, grading thresholds only vary slightly from one session to the next. Therefore, this grade calculator – which is based on the most recently available official thresholds – can still provide a reasonably useful reference for estimating your current performance level, even if it's not from the exact exam session you're taking.
Which variant should I choose?
Some options are chosen by you before the exam, such as the Core or Extended tier for Mathematics. However, other variants are assigned based on your school's time zone to ensure exam security. The grading thresholds may be different for different variants.
What are grading thresholds and weighting factor?
1. Grading Thresholds (Grade Boundaries)Definition:Grading thresholds (often called grade boundaries) are the minimum number of marks a candidate needs to achieve a particular grade (such as A*, A, or B) in a specific examination series.How they work:Because exam papers vary slightly in difficulty from year to year, exam boards do not use "fixed" percentages (e.g., 90% is always an A*). Instead, they adjust the thresholds after the exam has been sat to ensure it is no harder or easier to get a grade this year than it was last year.Example: If a Physics paper was exceptionally difficult, the threshold for an 'A' might be lowered to 45/80 marks. If the paper was easier, the threshold might rise to 55/80.2. Weighting Factor (Scaling)Definition:The weighting factor is a mathematical multiplier applied to the marks of individual "components" (papers) to ensure they contribute the correct proportion to the final syllabus grade.Why it is used:An IGCSE subject is usually made up of multiple papers (e.g., Paper 2, Paper 4, and Paper 6). Each paper may have a unique weighting factor. To calculate the final result, each paper’s raw mark is multiplied by its weighting factor to calculate the weighted mark. These weighted marks are then added together to create a single mark called "Total Weighted Mark", which is then compared to the latest grading thresholds to determine your final grade.
