Within the Human Interactions paper (02) - Options A or B could be assessed in either a number of structured questions or an essay question, and Options C or D could be assessed in either an essay question or a number of structured questions.
In the Human Interactions paper, the questions could be switched around so that Trade and Migration have the 16 mark questions and Human Rights and Power and Borders have the structured questions. This is so that we can assess the full range of content in these options. The structured questions could vary in tariff over time however the section totals and total marks for the paper cannot change so there will only be a little bit of variation.
The Practice Papers (available on Interchange) and the Sample Assessment Materials (A Level web page, within Assessment) show how these questions can vary as well as the papers from the last two summer series (2018 and 2019).
