Meta-ethics is a common theme for Year 2, building on a challenging unit from AS. Prescriptivism has been squeezed out, but you may want to get an overview to use in evaluation. The second theme develops Natural Law, and there are scarce resources on Finnis and, to a lesser degree, Hoose. With a ludicrously delayed text book in 2018, students will have struggled (motivating this site's contribution in April 2018). The ethical issues of immigration and capital punishment are also less common at A level. Have a look at the board's guidance, published in February 2018.
The Ethics course is completed by a detailed look at Free Will and Determinism, taking up a whole theme. You'll find plenty of resources for this topic, as it has been studied at A level for many years across the boards.
