For GCSE, pupils study both human and physical geography and, in addition to lessons which encourage the use of skills in geographical investigation, they participate in fieldwork. 

At AS a mixture of Human and Physical Geography is taught and pupils sit three structured answer papers on The Physical Environment, The Human Environment and Geographical Investigation.  At A2, examination is mainly by essay and the topics studied include coastal environments, tourism, urban problems and hazardous environments, in addition to a geographical investigation.
