How it is marked

What each part of the data question earns

Section B is one data question worth 34 marks. These are the marks the mark schemes give each part. Knowledge is knowing the idea, application is using the extract, analysis is the chain of reasoning, and evaluation is weighing it up.

PartWhere the marks come from
Calculate 2Application 2One mark for the method, one for the answer. The answer needs its unit (%, $, £) to get the second mark.
Explain 4Knowledge 2 + Application 2Make the point, then use a number or fact from the extract.
Analyse 6Knowledge 2 + Application 2 + Analysis 2Explain the chain of causes step by step. There are no marks for evaluation here.
Examine 8Knowledge 2 + Application 2 + Analysis 2 + Evaluation 2The same as Analyse 6, then one point that weighs it up.
Discuss 148 for knowledge, application and analysis + 6 for evaluationMarked in levels. Develop two or three points with the extract, then weigh them up.
Essay 2012 for knowledge, application and analysis + 8 for evaluationSection C: choose 2 of 3. Marked in levels.
From the real papers

What the past papers show

No short questions
Unlike Units 1 and 2 there is no section of 4-mark questions, and no Define or Draw command anywhere in the paper.
Q7 starts with a calculation
In all 11 papers we read, Q7(a) is Calculate 2: a percentage change, a change in total costs, or a four-firm concentration ratio. Q7(e) is Discuss 14.
Essays want a diagram
Most essays end “Illustrate your answer with an appropriate diagram”, and mark schemes cap answers without one at 9 of the 12 marks for knowledge, application and analysis. Labour-market essays usually leave this line out.
Two essays, not one
You write two 20-mark essays from three, so the essays are half the paper.
The night before

What to do tonight

Do not try to learn the whole unit again. Do these, then sleep.

  1. Draw the market structure diagrams from memory: perfect competition, monopoly, monopolistic competition, and a monopsony labour market.
  2. Practise the three Q7(a) calculations: percentage change, change in total costs, and a four-firm concentration ratio.
  3. Plan two essays: for each one, the diagram you would draw and the industry you would write about.

Every topic in Unit 3 has a free Practice tab. Marking of written answers is part of Pro.
