Understanding the IB Grading System
In the International Baccalaureate (IB) Diploma Programme, each subject is graded on a scale from 1 to 7, with 7 being the highest possible score. A “7” reflects:
- Excellent understanding and insight
- A clear ability to apply knowledge in unfamiliar situations
- Consistently strong performance in both internal assessments and final exams
Grade boundaries vary each year depending on difficulty and scaling. For many subjects, scoring a 7 means earning 80–90% of the total available marks.
Statistics: How Many Students Get Straight 7s?
Getting all 7s across six subjects is extremely rare. Here are the numbers:
- In most years, only 1% to 2% of students worldwide achieve a perfect 45
- Scoring 7s in math, physics, and English A is especially challenging
- Subjects like Language B or Environmental Systems tend to have slightly higher 7-rates
So yes—it’s possible, but only a tiny fraction of IB students achieve it.
What It Takes to Score a 7 in IB Subjects
Scoring a 7 isn’t about cramming. It requires:
- Deep conceptual understanding
- Mastery of subject-specific command terms (e.g., “evaluate,” “justify”)
- Integration of real-world examples and critical thinking
- Strong performance in Internal Assessments (IAs), often worth 20–30% of your final score
- Time management and balance across subjects
High scorers don’t just memorize—they learn to analyze, apply, and argue.
Are Some Subjects Easier to Score 7s In?
Yes, data suggests:
- Language B (e.g., French B SL) and Environmental Systems & Societies have higher 7-rates
- Math Analysis and Approaches HL, Physics HL, and English Literature A HL are among the toughest
- Group 6 (Arts) subjects can be unpredictable due to subjective marking
That said, it’s not about taking "easy" subjects—alignment with your strengths is more important.
Strategies Used by Students Who Get All 7s
Here’s what top IB scorers often do:
- Start early in DP1 and stay consistent
- Use active recall and spaced repetition
- Regularly practice with past papers and mark schemes
- Create concise, topic-specific notes
- Seek frequent feedback on IAs and practice essays
- Track progress and adjust weak areas
They don't wait for last-minute miracles—they build a routine that allows steady improvement.
Common Mistakes That Stop Students From Scoring 7s
Even smart students lose points by:
- Ignoring marking criteria or failing to understand what examiners want
- Focusing only on external exams and neglecting IAs
- Relying solely on textbooks and not exploring real-world examples
- Procrastinating on IA drafts, EE, and TOK
- Underestimating the impact of stress and burnout
Avoid these traps by staying disciplined, reflective, and proactive.
Can You Still Get a 45 Without All 7s?
Yes! You can get:
- 6 subjects x 6 points = 36 points
- Plus 3 bonus points from TOK and EE
- That gives you a total of 45, even if you score some 6s
Some students strategically plan to score a 6 in tougher HL subjects and aim for a full 3 in the core to balance their final score.
The Role of Teacher Support and Feedback
Teacher guidance is critical. Top students:
- Ask for detailed feedback on IAs and practice work
- Use marking rubrics to understand how they’re being graded
- Stay engaged in class and build rapport with instructors
If you’re unclear on your progress—speak up and ask.
Psychological Pressure of Aiming for All 7s
Pursuing perfection can take a toll:
- You might feel overwhelmed, anxious, or burned out
- Your social life and well-being may suffer
- The fear of failing a subject can be paralyzing
Instead of aiming for perfection, focus on balance, effort, and progress. Even top universities understand the IB’s rigor.
Conclusion: Is It Worth Aiming for All 7s in IB?
Scoring all 7s in the IB is incredibly difficult, but not impossible. If you're naturally disciplined, academically driven, and supported by strong teachers and resources—it’s an admirable goal.
However, the key is to work hard without compromising your mental health. Many universities would rather see a well-rounded, resilient student with a 41 than a stressed-out perfectionist chasing a 45.
FAQs
How many people get a 45 in IB?
Typically, less than 2% of candidates each year achieve a full 45.
Do top universities require all 7s?
No. Most elite universities accept students with 40–43, provided the rest of the application is strong.
Is 6 in HL still good?
Yes. A 6 in a Higher Level subject reflects excellent understanding and is highly respected.
Can I get a 45 without taking Group 6 (Arts)?
Yes. You can replace Group 6 with another Group 2, 3, or 4 subject and still achieve 45.
What’s harder: getting all 7s or getting a 45?
Getting all 7s is generally harder than getting a 45, because the core (TOK and EE) can compensate for one or two 6s.
Do predicted 7s mean I’ll score a 7?
Not always. Predicted grades are estimates, but final grades depend on exam performance and moderation.
