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 TOK marks should I enter?
TOK uses Essay and Exhibition at SL. Please enter each score out of the maximum marks shown.
Is the TOK calculator only for Standard Level (SL)?
Yes, currently this tool only supports SL. Please use the SL components (Essay and Exhibition) and SL TOK grade boundaries.
How much does Exhibition affect my TOK grade?
The Exhibition accounts for approximately 33% of your total TOK grade before boundaries are applied. Updating a predicted mark to a confirmed score will often improve the accuracy of your estimate more than adjusting individual paper scores.
