Paper structures, command terms, marking criteria, and proven exam techniques for IB ESS, Business Management, and Economics.
Two students with identical knowledge can score very differently. The difference is almost always exam technique — reading the question, structuring the answer, and allocating time correctly.
A 4-mark “Explain” question needs a different structure to a 4-mark “Describe”, even at the same marks. IB examiners mark against a specific mark scheme and reward the right structure as much as correct content.
Every IB exam question starts with a command term. Learn what each one demands and you'll stop losing easy marks.
| Command term | What it means | Answer structure | Marks |
|---|---|---|---|
| Define | Give a precise meaning | One clear sentence — no examples needed | 1–2 |
| Describe | State features or characteristics | Several factual points, no explanation | 2–4 |
| Outline | Give a brief account of main points | Key points only — breadth over depth | 2–4 |
| Explain | Give reasons or causes | Point + reason ("because…") | 3–6 |
| Suggest | Propose a plausible explanation or answer | Reasoned proposal with justification | 2–3 |
| Analyse | Break down and examine in detail | Multiple components with links between them | 4–6 |
| Evaluate | Make a reasoned judgment based on evidence | Strengths + weaknesses/limitations + conclusion | 6–9 |
| Discuss | Consider multiple perspectives | Both sides with evidence + balanced conclusion | 6–9 |

Master these before your exam — they apply in ESS, Business Management, Economics, and every other IB subject.
"Define", "Evaluate", "Discuss" — each word tells you exactly how many marks are available and what structure to use. Getting this wrong costs marks every time.
IB marks are worth roughly 1 minute each. A 6-mark question gets 6 minutes. Running out of time is one of the most preventable ways to lose marks.
PEEL paragraphs (Point → Evidence → Explanation → Link) for essays; structured data-reading for case studies. Examiners reward format as much as knowledge.
IB mark schemes are specific. Learning to write with the mark scheme in mind — using the right terminology and covering the expected points — is the fastest way to improve.
Most students study in the wrong order and wonder why their grades don't improve. Follow this sequence for every topic.

Exam Skills Guide →SL & HL from 2026 — counts as both Group 3 and Group 4
Pre-released case study. Apply ESS concepts to an unseen environmental scenario. Focus on systems diagrams, EVS, and data interpretation.
Covers all units. Section A is compulsory short-answer; Section B is essay choice. High-value marks from evaluating EVS, policies, and management strategies.
SL & HL — heavy focus on case study analysis and business tools
Pre-released unseen case study. Apply business tools (SWOT, STEEPLE, Ansoff) to a real-world company. Answers must reference the stimulus directly.
Tests all five units. Section A is compulsory; Section B is essay choice. HL adds Paper 3 (HL extension case study, 25 marks).
SL & HL — diagrams, real-world examples, and data-driven analysis
Answer one question from three. Part (a) tests explanation with diagrams (10 marks); Part (b) requires balanced evaluation with a judgment (15 marks). No calculator.
Real-world data and articles. Structured sub-parts from "Define" to "Evaluate" (15 marks). Calculator required. HL adds Paper 3 (Policy Paper, 60 marks).

IB command terms are specific verbs used in exam questions that tell you exactly what type of response is expected. Common terms include Define (1–2 marks, give a precise meaning), Describe (state the features), Explain (give reasons), Analyse (break down and examine), Evaluate (make a judgment with evidence), and Discuss (consider multiple perspectives). Each term corresponds to a specific answer structure and marks allocation.
IB ESS is assessed through two external papers and one internal assessment. Paper 1 (1 hour SL / 2 hours HL, 35–70 marks) tests data-based and short-answer questions across the syllabus. Paper 2 (2 hours SL / 2.5 hours HL, 60–80 marks) includes short answer and essay questions covering all units. The Internal Assessment is an individual investigation worth 25% (SL) or 20% (HL) of the final grade.
IB Business Management SL is assessed through Paper 1 (1.5 hours, pre-released case study, 30 marks) and Paper 2 (1.5 hours, structured questions, 40 marks). HL adds Paper 3 (1 hour 15 minutes, unseen stimulus, 25 marks). All exams require application of business tools like SWOT, PEST, and financial ratios to real scenarios.
IB Economics SL is assessed through Paper 1 (1 hour 15 minutes, extended response, 25 marks, 30%) and Paper 2 (1 hour 45 minutes, data response, 40 marks, 40%), plus an IA portfolio worth 30%. HL adds Paper 3 (1 hour 45 minutes, policy paper, 60 marks, 30%) and adjusts the weighting: Paper 1 (20%), Paper 2 (30%), Paper 3 (30%), IA (20%). Diagrams and real-world application are essential across all papers.
The fastest improvements come from: (1) learning command terms so you know exactly what each question asks for, (2) practising with real mark schemes to understand examiner expectations, (3) timed practice under exam conditions, and (4) reviewing common mistakes specific to your subject.
