📝 Extended Essay (EE)
What it is:
An independent 4,000-word research paper on a topic of your choice within an IB subject area
Duration:
Written throughout both years of the IB Diploma (typically 10-15 hours supervised writing)
Focus:
Developing original research argument, demonstrating critical thinking, conducting literature review, and presenting findings formally
Grading:
Awarded A-E grades (A = 12-15 marks, B = 9-11 marks, C = 7-8 marks, D = 5-6 marks, E = 1-4 marks, or 0 if non-submitted)
Subject Choice:
Can be written in any IB subject (most common: English, History, Economics, Science subjects). Must align with IB course content.
💭 Theory of Knowledge (TOK)

An integrated course exploring epistemology (how we know what we know) and making connections across all IB subjects
Duration:
100 hours of teaching across the two-year program. Includes essays and presentations.
Focus:
Critical thinking about knowledge, understanding different knowledge approaches (arts, sciences, history, etc.), connecting theory to real-world situations
Assessment:
Essay exam (1,200-1,600 words) and class presentation/discussion. Graded A-E (A = 8/10, B = 6-7/10, C = 4-5/10, D = 2-3/10, E = 0-1/10)
Key Themes:
Knowledge questions, ways of knowing, areas of knowledge, perspectives and biases, reliability of knowledge sources
The EE/TOK Bonus Points Matrix
Your Extended Essay and Theory of Knowledge grades combine in a specific matrix to determine your bonus points. Here's exactly how the system works:
📊 Official EE/TOK Matrix
| Theory of Knowledge | A | B | C | D | E |
|---|---|---|---|---|---|
| EE: A | 3 | 2 | 0 | 0 | 0 |
| EE: B | 2 | 1 | 0 | 0 | 0 |
| EE: C | 0 | 0 | 0 | 0 | 0 |
| EE: D/E | 0 | 0 | 0 | 0 | 0 |
Note: Highlighted cells show the combination you receive (e.g., A in EE + A in TOK = 3 bonus points, shown in green highlight)
🔍 How to Read the Matrix
Find your EE grade (left column)
Look at the row corresponding to your Extended Essay grade (A, B, C, D, or E)
Find your TOK grade (top row)
Look at the column corresponding to your Theory of Knowledge grade (A, B, C, D, or E)
Read the intersection
Where your EE row and TOK column meet shows your bonus points (0, 1, 2, or 3)
Example:
EE grade A + TOK grade A = Look at A row, A column = 3 bonus points (maximum)
Another example:
EE grade B + TOK grade A = Look at B row, A column = 2 bonus points

Frequently Asked Questions About EE/TOK Matrix
❓ What if I get a C grade in EE or TOK?
If you receive a C in either the Extended Essay or Theory of Knowledge, you earn 0 bonus points. Looking at the matrix, any grade C or below in either component results in 0 bonus points. Additionally, receiving a C or lower in either component may result in non-award of the IB Diploma - you need minimum grades to actually receive your diploma. Even if you don't lose the diploma, a C means you miss out on potentially 1-3 bonus points that could help meet university requirements.
❓ Can I get bonus points if my subjects don't add up?
Yes! EE/TOK bonus points are completely independent of your subject grades. You could have low subject scores but still earn 3 bonus points if you get A grades in both EE and TOK. Conversely, you could have high subject scores (42 points) but earn 0 bonus points if you get Cs in EE/TOK. The matrix is separate - focus on doing well in both components regardless of your subject performance.
❓ How is the final TOK grade determined?
Your TOK grade is based on two components:
- TOK Essay (50%): 1,200-1,600 word essay in response to one of three prescribed TOK essay questions. Graded by external examiners.
- TOK Presentation/Oral (50%): 10-minute individual presentation or small group activity demonstrating understanding of TOK concepts. Assessed by teachers.
These two components combine to give your overall TOK grade (A-E), which then feeds into the EE/TOK matrix.
❓ Can universities see my EE and TOK grades separately?
Yes, universities can see your individual EE and TOK grades on your official transcript. They're not hidden in the combined matrix - they appear separately. If you achieve A in both, universities will see this and recognize your strong performance in both independent research and critical thinking. Some universities specifically value strong EE grades (showing research ability) and strong TOK grades (showing intellectual breadth). Make these strengths visible in your application materials.
❓ How important are the 3 bonus points for university admissions?
The 3 bonus points can be the difference between admission and rejection at top universities. Examples:
- Cambridge requires 40 for many programs. 3 bonus points can take you from 37 (subjects) to 40 (total)
- Ivy Leagues expect 40+. 3 bonus points can bridge the gap from 37 subjects to 40 total
- Conditional offers specify exact points needed. Bonus points help you meet those conditions
Every point matters. Don't underestimate the significance of maximizing your EE and TOK grades.
❓ Which is easier to improve: EE or TOK grade?
This depends on your strengths, but Extended Essay tends to be more controllable:
- EE: You control topic choice, research depth, writing quality. Your supervisor provides extensive feedback. More opportunities to revise and improve.
- TOK: Broader range of assessment (essays + presentations). Depends on exam performance and classroom discussion participation. Less time for revision between submissions.
Strategy: Invest heavily in EE from the start (choose great topic, start early), then focus on TOK essay preparation and presentation skills.
