IB Biology Score Scale
The IB Biology scoring system converts your raw exam scores into a final grade ranging from 1 to 7. These grades reflect your understanding and mastery of the subject. Here’s a breakdown of how raw scores typically translate into the course grade scale, although exact boundaries can vary slightly each year.
Table: Estimated Grade Boundaries for IB Biology
| Raw Score Range (%) | Final Grade (1-7) |
|---|---|
| 0-20 | 1 |
| 21-35 | 2 |
| 36-50 | 3 |
| 51-65 | 4 |
| 66-80 | 5 |
| 81-90 | 6 |
| 91-100 | 7 |
These boundaries are indicative and can be adjusted based on the annual standardization process which takes into account the overall performance of students worldwide.

Common Questions
1. How is the final IB Biology grade calculated?
The final grade for IB Biology, whether at Higher Level (HL) or Standard Level (SL), is determined by a combination of internal assessments (20% of the final grade) and external examinations (80%). The exams consist of multiple papers: Paper 1 (multiple choice), Paper 2 (short answer and extended response), and Paper 3 (option topics), each contributing differently to the total score.
2. Are the grading boundaries different for HL and SL?
Yes, grading boundaries typically differ between HL and SL due to the varying levels of difficulty and content depth. HL students are often required to achieve a higher raw score to receive the same grade as SL students, reflecting the increased challenge level.
3. What happens if I’m close to a grade boundary?
IB grades are moderated globally, which means if you’re close to a boundary, your score might be subject to review. Sometimes, slight adjustments are made to account for the difficulty of the exam and overall student performance that year.
4. Can I improve my grade after the results are released?
Yes, you can request a re-evaluation or retake the exam in the next session if you believe there’s been an error or if you’re aiming for a higher score. Keep in mind, though, that scores can also be adjusted downward upon re-evaluation.
5. How important are the internal assessments?
Internal assessments are crucial as they account for a significant portion of your final score (20%). Excelling in these projects can provide a strong buffer and significantly impact your final grade, especially if your exam performance doesn’t go as planned.
Understanding the scoring system can help you better prepare and set realistic goals for your IB Biology course. Whether you’re tackling HL or SL, knowing these nuances can make a big difference in how you approach your study and exam strategies! 📘💪
