Component Breakdown
⚠️ Important Accuracy Notice: This calculator uses approximate grade boundaries from historical data. Official boundaries vary by session and timezone (sometimes by ±3-5% or more). Component weightings may not reflect the latest IB curriculum changes. Always consult your IB coordinator for official predicted grades.
Grade boundaries are approximations based on publicly available information. For official IB grade boundaries and statistics, visit ibo.org or request them from your school's IB coordinator.

Frequently Asked Questions
How accurate are these predicted grades?
Our calculator uses approximate grade boundaries based on historical IB examination data. Grade boundaries vary significantly between sessions (typically ±3-5%) and differ by timezone. For the most accurate predictions, consult your IB coordinator and check the official IB grade boundaries published after each exam session on the IB website.
What scores should I enter for each component?
Enter your actual marks from mock exams, practice papers, coursework, and Internal Assessments. If you haven't completed all components yet, use your best estimate based on similar past work.
Why do grade boundaries change each session?
The IB uses a statistical process to ensure grades remain consistent over time. If papers are more difficult, boundaries may be lower. If they're easier, boundaries may be higher. This maintains the integrity of each grade level.
Can I predict grades for multiple subjects?
Yes! Simply change the subject in the dropdown to calculate predictions for each of your IB subjects. Each subject has its own specific assessment structure and grade boundaries.
What if my predicted grade is lower than I hoped?
The calculator shows exactly how many percentage points you need to reach the next grade level. Focus your revision on the highest-weighted components where you can make the biggest impact.
Are these the same boundaries used by IB examiners?
These are approximate boundaries based on historical data and publicly available information. Official IB grade boundaries are determined after each exam session through statistical analysis and vary by timezone and session. For official boundaries, request them from your IB coordinator or check the IB's published grade statistics.
Where can I find official IB grade boundaries?
Official grade boundaries are released by the IB to schools after each examination session. Your IB coordinator can provide you with the exact boundaries for your session and timezone. The IB also publishes statistical bulletins with grade distribution data on their website (ibo.org).
Where to Find Accurate IB Grade Information
For the most accurate and up-to-date IB grade boundaries and assessment information, use these official resources:
Your IB Coordinator
Your school's IB coordinator has access to official grade boundaries for your specific session and timezone. They can provide the most accurate predicted grades based on current IB standards.
IB Official Website
Visit ibo.org for official subject guides, assessment criteria, and statistical bulletins showing grade distributions across subjects.
Subject-Specific Resources
The IB publishes detailed subject guides with exact component weightings, assessment criteria, and mark schemes. These documents are updated regularly to reflect curriculum changes.
Understanding IB Grade Boundaries
The International Baccalaureate uses a sophisticated statistical process to set grade boundaries that ensure consistency across examination sessions. Each IB subject is assessed through multiple components - typically including externally assessed papers and internally assessed coursework.
Important Note on Accuracy:
This calculator uses approximate grade boundaries based on historical data and publicly available information. Official IB grade boundaries vary by session, timezone, and year - sometimes by ±3-5 percentage points or more. The component weightings and maximum scores may also differ from the current IB curriculum. Always consult your IB coordinator for official predicted grades and up-to-date boundaries.
Despite these limitations, the calculator is valuable for understanding the relative weighting of different assessment components. Since Internal Assessments often carry 20-25% of the total marks, improving these can significantly impact your final grade. Use this tool to identify which components have the greatest effect on your overall score.
Remember that predicted grades are estimates based on your current performance. With focused revision and improvement in key areas, you can often exceed your predicted grade in the final examinations. Use this tool as a rough guide to focus your efforts, but rely on your teachers and official IB resources for accurate predictions.
