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 Spanish B marks should I enter?
Please enter the scores for Paper 1, Paper 2: Reading, Paper 2: Listening, and Internal Assessment (Oral) corresponding to your level. Ensure you match the maximum marks shown so that the Spanish B weightings are applied correctly.
Do SL and HL Spanish B use the same calculator settings?
No. Level changes Spanish B maxima, weightings, and which boundary table is applied—even when component names match.
How much can the Spanish B oral change my predicted grade?
The oral component accounts for approximately 25% of your Spanish B 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.
