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

Understanding Your Strengths and Weaknesses

A prediction of 39/45 may show you're strong in sciences but weak in literature. This insight allows targeted study and resource allocation.

Adjusting Your Study Plan Accordingly

Focus more time on subjects below your target grade. Use RevisionDojo’s other resources for topic reviews, IA support, and revision tips.

Real-Time Updates and Boundary Adjustments

RevisionDojo monitors changes to IB assessments and adjusts predictions accordingly—ensuring you're always working with current data.

Clean Interface and Easy Navigation

Common Mistakes to Avoid When Using Grade Predictors

  • Guessing input data: Use actual scores or accurate estimates.
  • Ignoring core components: TOK and EE have a big impact.
  • Relying solely on predictions: Use them to guide—not replace—teacher feedback and study.
