It carries 70 marks over three hours and has 30 compulsory questions in four sections: eight one-mark, ten two-mark, nine three-mark and three five-mark questions.

One five-mark option is built around a diagram of ovarian events labelled 'a' to 'i', and a short question asks how Ahmed Khan of Bangalore tackled plastic waste.
