Historical Grade Trends
Frequently Asked Questions
How does the IB grade calculator work?
It combines the marks you enter for each assessment component using official IB weightings, then maps the weighted total to historical grade boundaries for the session you select.
How accurate are the grade predictions?
Predictions follow official weightings and past-session boundaries. Your live result can still differ if your exam session’s boundaries shift or if entered marks are estimates.
Should I enter predicted marks?
Yes when a component is not final yet. Replace estimates with confirmed IA, oral, or coursework marks as soon as you have them for a tighter prediction.
Why does changing the exam session change my grade?
Boundaries are session-specific. The same weighted total can map to different grades under different May or November grade boundaries.
Which French ab initio marks should I enter?
French ab initio uses Paper 1, Paper 2: Reading, Paper 2: Listening, and Internal Assessment (Oral) at SL. Please enter each score out of the maximum marks shown.
Is the French ab initio calculator only for Standard Level (SL)?
Yes, currently this tool only supports SL. Please use the SL components (Paper 1, Paper 2: Reading, Paper 2: Listening, and Internal Assessment (Oral)) and SL French ab initio grade boundaries.
How much can the French ab initio oral change my predicted grade?
The oral component accounts for approximately 25% of your French ab initio grade. You can try adjusting your oral mark by ±2 to see if it moves you across the next grade boundary. Paper variants can differ by timezone; match the table to the papers your school sat.
