What Is an IB Grade Predictor?
An IB Grade Predictor is an intelligent tool designed to estimate your final IB Diploma score based on current or projected performance in each subject, including your Theory of Knowledge (TOK) and Extended Essay (EE) results. It calculates your predicted overall score out of 45 points using grade boundaries and official IB assessment data.
Whether you're preparing for your May 2025 exams or just beginning the IB journey, using a grade predictor empowers you to take charge of your academic trajectory with confidence and clarity.
How Does the IB Grade Predictor Work?
Input: Subject Grades, TOK, and EE
You enter your Higher Level (HL) and Standard Level (SL) subject scores, as well as your predicted grades in TOK and the EE. These components contribute up to 45 total points, with 3 core points from the combination of TOK and EE.
Output: Predicted Total Score and Core Points
The tool uses historical and projected grade boundaries to convert raw marks into official IB grades (1–7). It then totals the individual subject grades and core points to generate your final predicted score.
Why Predict Your IB Grades?
Set Realistic Goals and Improve Performance
Understanding where you stand helps you focus your efforts. If your grade in Biology SL is close to a 6 but could drop to a 5, the predictor alerts you early so you can prioritize that subject in your revision plan.
Plan University Applications with Confidence
Many university offers are conditional on final IB scores. Knowing whether you’re likely to meet a 38-point requirement helps you strategize applications, interviews, and scholarship opportunities.

IB Grading Explained: How Scores Are Calculated
Subjects (HL/SL) and Core Components
Each of the six subjects is graded from 1–7. TOK and EE contribute up to 3 additional core points, based on a matrix of grades (e.g., A in TOK and B in EE = 2 points).
Grade Boundaries and Scaling
Grade boundaries shift slightly every year. For example, in May 2024, a 7 in English HL required 82%+, whereas in May 2025, the boundary might adjust based on cohort performance. RevisionDojo tracks these trends and updates its tool accordingly.
How to Interpret Your Predicted Score
