How to Interpret Your Grade from the Tool
The embedded grading tool provides a score out of 34, which corresponds to the following grade bands:
A (Excellent): 27–34
B (Good): 21–26
C (Satisfactory): 14–20
D (Mediocre): 7–13
E (Elementary): 0–6
If your score falls between bands or you're uncertain, focus on the criteria where you scored lower and consider the following improvement actions:
Focus and Method: Refine your research question and ensure your methodology is appropriate and well-explained.
Knowledge and Understanding: Deepen your understanding of the topic and use technical terms accurately.
Critical Thinking: Enhance your analysis and evaluation; support your arguments with evidence.
Presentation: Organize your essay logically and adhere to formatting guidelines.
Engagement: Reflect thoughtfully on your research process in the RPPF.
Annotated Examples
High-Band Excerpt:
"The implementation of the Dijkstra algorithm in this study resulted in a 15% improvement in pathfinding efficiency compared to the A algorithm under similar conditions. This suggests that, for scenarios with uniform cost, Dijkstra's algorithm may offer superior performance."*
Why It Scores High: This excerpt demonstrates clear analysis, comparison of algorithms, and a well-supported conclusion, reflecting strong critical thinking.
Mid/Low-Band Excerpt:
"I used Dijkstra's algorithm and found it to be better than A."*
What's Missing: Lacks detailed analysis, specific data, and a clear explanation of why Dijkstra's algorithm performed better.
Grade Boundaries & Converting Your Mark
The Extended Essay is graded out of 34 marks, which correspond to the following grade boundaries:
Grade
Mark Range
A
27–34
B
21–26
C
14–20
D
7–13
E
0–6
These grades contribute to the overall IB Diploma score, with the Extended Essay and Theory of Knowledge components combined to award up to 3 additional points.
Common Mistakes & Fast Fixes
Vague Research Question → Refine to a specific, focused question.
Inappropriate Methodology → Choose methods suitable for your research question and justify them.
Superficial Analysis → Provide in-depth analysis and support conclusions with evidence.
Poor Organization → Structure your essay logically with clear headings.
Inconsistent Formatting → Adhere to IB formatting guidelines throughout.
Subject-Specific Tips
Algorithm Analysis: Include time and space complexity evaluations.
Software Development: Document development processes and testing methodologies.
Impact Studies: Use case studies and statistical data to support arguments.
FAQs
Q: How important is the Research Question in the EE?
A: It's crucial; a well-defined question guides your research and analysis.
Q: Can I include personal opinions in my EE?
A: Yes, but they must be supported by evidence and analysis.
Q: How should I format my citations?
A: Use a consistent citation style (e.g., APA, MLA) throughout your essay.
Q: What if my findings contradict my hypothesis?
A: Discuss the discrepancies and analyze possible reasons; this demonstrates critical thinking.
