How to Calculate My Predicted Grade in IB? | Step-by-Step Guide

Step 4: Apply the Weighting Formula

Use the weighting for the subject (typically provided in the syllabus):

Example for HL Science:

• IA: 20%
• Paper 1–3: 80%

Predicted Score = (IA % x 0.2) + (Exam % x 0.8)
Example: (83.3% x 0.2) + (72% x 0.8) = 16.66 + 57.6 = 74.26%

Step 5: Match Your Final % to the IB Grade Boundaries

Refer to IB grade boundaries (can vary by year and subject):

In our example, a score of 74.26% corresponds to a predicted grade of 6.

How to Calculate Your Total Predicted IB Score

Repeat the above steps for all six subjects, then:

• Add the predicted grades for each subject (max 42)
• Add predicted points from TOK + EE (up to 3)

Total Predicted IB Score = Subject Grades (max 42) + Core Points (max 3)
Example:

• 3 HL subjects: 6, 6, 5
• 3 SL subjects: 6, 5, 5
• TOK/EE Bonus: 2
  Total: 6+6+5+6+5+5 = 33 + 2 = 35
