How to Succeed in Economics Paper 3

 

  • Solve past papers – This helps you get used to the type of questions that could be asked on the exam and helps you develop skills in learning which concepts to apply. You should try to solve past papers using a timer to simulate exam conditions and check your answers against a markscheme to identify areas for improvement.

     

  • Memorize relevant formulae –  Paper 3 contains a significant number of calculations and no formula sheet is provided. Students are expected to memorize and recall the relevant equations needed. Students should memorize the main equations from each section of the syllabus. Create flashcards to help you study the equations. You could also take a blank piece of paper and write down each formula by hand to help you remember it. 

     

  • Show your working – This is especially important for calculation questions. Make sure to show all your working, as you will be able to receive part marks in case your final answer is incorrect. 

     

  • Review the HL content – Since Paper 3 is an HL-only paper, it will test the knowledge from HL areas in more depth, so make sure to thoroughly revise HL topics. However, ensure you also revise the other syllabus content as it can help strengthen your arguments in Paper 3. 

     

  • Plan before writing Organize your thoughts before beginning your essay to ensure your response stays focused and well-structured. Use the PEEL (Point, Evidence, Explanation, Link) structure when justifying a policy in your evaluation parts. Before you start writing, create a quick draft in bullet points of what you want to base your answer on. Do not simply rush to begin writing, as this could lead to your thoughts being disorganized, which could impact the examiner's perception of the quality of your response.
