IB Extended Essay Guide 2025 Update | Subjects/Tips & Changes
The IB Extended Essay (EE) is a 4,000-word independent research paper mandatory for Diploma Programme (DP) students. For 2025 submissions (first assessed May 2027), key updates include two pathways—subject-focused or interdisciplinary—new 30-mark criteria emphasizing framework, analysis, evaluation, and reflection, plus stricter AI ethics rules.
May 2025 DP stats show an 81.26% pass rate (avg. 30.58/45), but only 20-25% of EEs score A-grade. Top subjects: English A and Biology. Avoid pitfalls like broad research questions (30% of low scores), poor citations (25%), and weak analysis (20%).
This guide covers Groups 1-6 tips with example RQs, common mistakes table, free template, tools like Zotero, and student stories. For basics, check our older guide. Ready to ace it?
IB Extended Essay Guide 2025
The IB Extended Essay challenges you to dive deep into a topic of your choice, producing a 4,000-word paper that showcases research, critical thinking, and writing skills. It’s one of three core DP components (with TOK and CAS), contributing up to 3 bonus points toward your diploma.
With 2025 updates rolling out—new pathways, revamped criteria, and AI guidelines—this guide is your roadmap. Whether you’re in Grade 11 starting your RQ or revising in Grade 12, we’ll cover everything: changes, subject strategies, stats, tools, and real student insights. Let’s turn overwhelm into an A-grade EE.
What is the IB Extended Essay?
The EE is a self-directed, supervisor-guided research project (~40 hours over 18 months). Pick one DP subject (or two for interdisciplinary) and craft an analytical RQ. Submit with RPPF (Reflections on Planning and Progress Form) and a viva voce interview.
Key Requirements:
- Word Count: 4,000 max (excludes abstract, contents, references, appendices, reflections).
- Timeline: Begins early Grade 11; draft deadlines mid-Grade 12; final submission January Grade 12.
- Scoring: 34 max (now 30 under new criteria); grades A-E.
- Purpose: Builds university-level skills; 81.26% DP pass rate in May 2025 highlights its impact.
Miss the EE? No diploma. But nail it, and boost your profile for top unis.
2025 Updates: What IB Students Need to Know
Major changes launch February 2025 for first assessment May 2027. The guide is now shorter and visual, with infographics for clarity.
New Pathways:
- Subject-Focused: Traditional deep dive into one Group 1-6 subject.
- Interdisciplinary: Blend two subjects (evolves World Studies EE), ideal for complex issues like climate-econ links.
Refined Assessment Criteria (30 marks total):
| Criterion | Marks | Focus |
|---|---|---|
| A: Framework for the Essay (RQ, methods, structure) | 6 | Effective setup? |
| B: Knowledge & Understanding | 6 | Subject integration? |
| C: Analysis & Line of Argument | 6 | Critical argument? |
| D: Discussion & Evaluation | 8 | Findings evaluation? |
| E: Reflection | 4 | Learner growth? |
Grade Boundaries (Indicative): A: 27-30, B: 21-26, C: 14-20, D: 7-13, E: 0-6.
AI Ethics: Cite prompts/tools/dates; no full generation. Academic integrity is non-negotiable—plagiarism/AI misuse = fail.
These shifts reward focused frameworks and personal reflection over rote description.
Stats & Common Mistakes to Avoid
May 2025 DP results: 202,103 students, avg. score 30.58/45, 81.26% pass. EE/TOK bonuses push many over the line. English A/Biology lead A-grades (~20-25%); Math/Arts lag.
Top 5 Mistakes (Estimated % Impact on Low Scores):
| Mistake | % Impact | Quick Fix |
|---|---|---|
| Broad/Descriptive RQ | 30% | Narrow + analytical (e.g., “impact of” vs. “how does X cause Y?”) |
| Weak Sources/Citations | 25% | 10+ primary; Zotero + MLA/APA |
| No Critical Analysis | 20% | Argue/evaluate, don’t summarize |
| Poor Structure/Reflection | 15% | Follow template; 500-word RPPF |
| Word Count/Plagiarism Issues | 10% | 3,800-4,000 words; scan with Turnitin |

IB EE Subjects Tips: Groups 1-6 Guide
Choose from 30+ subjects across 6 groups. Match your strengths—e.g., lab-savvy? Sciences. Wordy? Group 1.
Overview Table:
| Group | Subjects | Example RQ | Common Pitfalls | Pro Tips |
|---|---|---|---|---|
| 1: Studies in Lang/Lit | English/French Lit | “How does Austen use nature in Emma to reflect character development?” | Plot summary | Close textual analysis + 2-3 critics |
| 2: Lang Acquisition | Spanish B/Ab Initio | “How effective are memory palaces for Mandarin vocab retention?” | Psych crossover | 70% target language sources |
| 3: Individuals & Societies | History/Econ/Psych | “To what extent did minimum wage hikes reduce youth unemployment in the UK (2010-2020)?” | Narrative history | Stats/models + counterarguments |
| 4: Sciences | Bio/Chem/Physics | “Does hand sanitizer efficacy vary against E. coli strains?” | No replicates | Lab design: controls, ethics form |
| 5: Mathematics | Math AA/AI | “Can Alhazen’s billiard problem be solved via geometric series?” | Calc dumps | Original proofs + visuals |
| 6: Arts | Visual Arts/Music | “How does Luc Tuymans’ Mwana Kitoko critique colonial gaze?” | Description only | Artist intent + socio-context |
Group 1 Deep Dive: Focus on literary techniques/themes. Pitfall: Retelling plot. Tip: RQ like “satire in Pride & Prejudice,” cite primary + scholars.
Group 3 Example: Econ—use regressions; History—primary docs.
Group 4 Labs: Bio star—design experiments with variables.

Student Stories: Real-ish Lessons from the Trenches
Bio Lab Success (A Grade): “Sarah (Grade 12) procrastinated but turned it around with a hand sanitizer E. coli experiment. Replicates + stats got her 28/30. ‘Data doesn’t lie—visuals sealed it.'”
History RQ Fix (C to A): “Alex’s broad ‘WWII causes’ RQ tanked early drafts (C). Supervisor narrowed to ‘USSR-Finland Winter War diplomacy.’ Primary treaties + eval = A. Lesson: Iterate RQ early.”
Interdisciplinary Win: “Mia blended Psych-Econ on nudge theory in spending. New pathway rocked; reflection on biases earned E:4/4.”
Math Struggle: “Too advanced proofs dropped Jamal to B. Tip: Scale to AA HL level, add diagrams.”
