Are you stressing over what your IB results might be? Wondering whether you’ll get the diploma, meet your university offers, or hit your target grades?

You're not alone—and that's exactly why tools like IB Predict and the RevisionDojo IB Grade Predictor exist. These calculators help you input your predicted marks and estimate your final IB score based on real grade boundaries and IB diploma rules.

In this article, we’ll walk you through how to predict your IB grades, what tools to use, and why RevisionDojo offers a top-tier, ethical experience to help students, teachers, and coordinators.

What Is IB Predict and Why Do IB Students Use It?

IB Predict is a free, web-based tool that helps students estimate their final diploma points by entering subject grades and core components like TOK and the Extended Essay.

It uses:

  • Historical grade boundary data (like May 2023 or May 2025 exams)
  • Timezone-specific inputs for accuracy
  • Rules from the IB Diploma Programme to determine eligibility

How Does IB Predict Work?

To get a prediction using IB Predict:

  1. Visit RevisionDojo.
  2. Choose your exam session (e.g., May 2025, November 2024)
  3. Select your timezone or region
  4. Enter your predicted grades or raw scores for each subject
  5. Add your TOK and EE predicted grades
  6. Instantly view:
    • Total diploma points
    • Subject breakdown
    • Diploma eligibility status

It's quick, visual, and gives students clarity on where they stand.

Why Predicting IB Grades Is Useful

Whether you're a student preparing for finals or a teacher estimating predicted grades for university applications, these tools provide:

  • A clear target for your final revision efforts
  • Insight into grade boundaries, showing how close you are to the next level
  • Diploma award status, including core point calculations
  • Realistic expectations and improved goal setting

What Are IB Grade Boundaries and Why Do They Matter?

Every subject and exam session has specific grade boundaries—e.g., to get a 7 in IB Biology SL in May 2025, you might need 74% or higher.

Grade predictors use these boundaries to translate your raw marks into final IB grades. This is what makes tools like IB Predict and RevisionDojo incredibly accurate when used correctly.

How to Predict Your IB Score Like a Pro

Want an accurate idea of your final IB score? Follow these steps:

  • Step 1: Use your IA and mock scores (not just guesses)
  • Step 2: Check the exam session grade boundaries on IB Predict or RevisionDojo
  • Step 3: Be honest about what you’ve earned so far and what you can still improve
  • Step 4: Use RevisionDojo to identify which papers need the most work

Important: Prediction ≠ Guarantee

No tool can perfectly predict your final IB results. These tools are estimates based on past data, not future certainties.

Factors like:

  • Your actual performance on exam day
  • Examiner marking styles
  • Variations in grade boundaries from year to year

All affect your final scores. Use these tools for planning and motivation, not as a final answer.
