✅ Quick Answer: In Many Subjects, Yes—80% Can Be Enough for a 7
Scoring 80% or above on an IB exam often places you within the range needed for a level 7, especially in subjects where the grade boundaries are tight. However, this varies by subject, exam paper, and year.
📘 What Is a 7 in the IB?
In the IB Diploma Programme, subject grades range from 1 (lowest) to 7 (highest). A 7 means “excellent performance”—usually achieved by the top 5–7% of students globally.
🧮 How Are IB Grades Calculated?
Your final score per subject includes:
- External exams (Paper 1, 2, 3) – ~70–80% of total score
- Internal Assessment (IA) – ~20–30% of total score
- Weightings vary by subject and level (SL vs HL)
🎯 Typical Score Ranges for a Level 7
SubjectApprox. % Needed for a 7
Math AA HL 75–85%
Biology SL 80–90%
Economics HL 75–85%
English Literature 80–85% (strong essay scores)
History HL 70–80%
Physics HL75–85%
Note: Boundaries change slightly each year based on global performance.
🔍 Why 80% Isn’t Always Enough—or Always Required
- Some harder subjects (like Math HL or Physics HL) may award a 7 with as low as 72–75%
- In easier-marking years or lower-curve subjects, you might need closer to 85–90%
- Internal Assessment scores can significantly boost or lower your final grade
💡 Tips to Aim for a 7
1. Maximize IA Scores
Internal assessments are predictable and controllable—do well here to give yourself a cushion.
2. Master Command Terms
Understanding exactly what the IB expects in responses is key—especially in essay-based subjects.
3. Use Markschemes and Past Papers
Grade boundaries are just numbers—train your accuracy using real examiner markschemes.
4. Study Smart, Not Just Hard
Focus on high-frequency topics, exam timing, and common pitfalls in each subject.
