Understanding the IB Grading System
The International Baccalaureate (IB) Diploma Programme uses a standardized grading scale from 1 to 7, where:
- 7 = Excellent performance
- 6 = Very good
- 5 = Good
- 4 = Satisfactory
- 3 = Mediocre
- 2 = Poor
- 1 = Very poor (failing)
Students must take six subjects, typically split into:
- 3 Higher Level (HL) courses – more depth, more teaching hours
- 3 Standard Level (SL) courses – foundational, with fewer hours
Alongside these subjects, students must complete the core components: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS). These contribute up to 3 bonus points toward the diploma.
The Official IB Diploma Pass Criteria
To receive the IB Diploma, students must:
- Score at least 24 points total
- Have no grade 1 in any subject
- Have no more than two grade 2s across HL and SL
- Score at least 12 points total across all HL subjects
- Score at least 9 points across SL subjects
- Complete and pass the core components (TOK, EE, and CAS)
These rules allow a small margin for underperformance, but only if it is compensated for elsewhere.
Is It Possible to Pass With a 2 in an HL Subject?
Yes—you can still get your diploma if you score a 2 in one HL subject, but only if:
- You have only one 2 total across all six subjects
- Your other two HL subjects bring your HL total to 12 or more
- You have no 1s in any subject
- You meet the SL and core requirements
Example:
- HL: 2, 5, 5 → 12 points ✅
- SL: 6, 5, 4 → 15 points ✅
- Core (TOK/EE/CAS): Passed ✅
- Total = 27 points ✅
✅ Diploma awarded
When a 2 in HL Will Disqualify You
Even one 2 can cost your diploma if:
- You have two or more 2s in any combination (HL or SL)
- Your total HL score is less than 12
- You have a grade 1 in any subject
- You fail the core components (TOK, EE, or CAS)
These are automatic fail conditions, regardless of your total score.
Example Scenarios With a 2 in HL
✅ Passing Scenario:
- HL: 2, 6, 4 → 12 points
- SL: 6, 5, 4 → 15 points
- Total: 27 points
- Core passed
→ Diploma awarded
❌ Failing Scenario:
- HL: 2, 4, 5 → 11 points (fails HL requirement)
→ Diploma not awarded
❌ Failing Scenario:
- HL: 2, 2, 5 → 9 HL points (too many 2s + HL fail)
→ Diploma not awarded
How to Compensate for a Low HL Score
If you’re underperforming in one HL subject, here’s how to stay on track:
- Aim for high scores in your other two HLs (6+)
- Maximize your SL scores to exceed 9 points easily
- Score well in TOK and EE to earn up to 3 bonus points
- Submit strong Internal Assessments (IAs) for subjects where you struggle
- Get feedback early to improve weak areas
Bonus points can be the difference between passing and failing when you're on the edge.
Preventing Low Scores in HL Exams
To avoid hitting the dreaded 2 in any subject, especially HL, focus on:
- Using past papers to understand exam style and command terms
- Mastering your subject syllabus—every topic can show up
- Practicing with timed assessments to simulate pressure
- Studying using active recall and spaced repetition
- Getting feedback from teachers and peer reviews on essays and IAs
Preparation and technique matter more than just content memorization.
What to Do If You’re At Risk of a 2 in HL
If your mocks or early assessments suggest a risk of scoring 2:
- Meet with your teacher to identify weaknesses
- Create a revision plan targeting those areas
- Use IB-specific study platforms like RevisionDojo to drill concepts
- Request additional support or tutoring
- Consider applying for a remark or retake if the final score is borderline
You’re not stuck—IB does allow second chances through exam retakes.
Final Thoughts on Low HL Scores and the Diploma
Scoring a 2 in an HL exam is not the end of the world. The IB grading policy allows some room for underperformance, but only if you're strong in other areas.
The key is balance and awareness—know where you stand and make sure your overall profile meets the requirements. IB isn't just about perfection—it's about perseverance, strategy, and smart effort.
FAQs
Can I get the diploma with a 2 and still go to university?
Yes. Many universities accept students with a 2 in one subject as long as the diploma is awarded.
Do HL grades matter more?
Yes, slightly. HL subjects are more in-depth and require more hours, and you must earn at least 12 HL points.
How many 2s can I get and still pass?
You may have only one grade 2 in total. Two 2s (in HL or SL) disqualify you.
What if I get a 1 in an SL subject?
Any grade of 1 automatically disqualifies you from earning the diploma.
Do bonus points make a difference?
Absolutely. Up to 3 bonus points from TOK and EE can boost your total and help you meet the 24-point minimum.
Can I retake an HL exam to improve my score?
Yes. You can retake exams in the next session (May or November) to raise your grade and qualify for the diploma.
