Very useful and a lot of good key material.

Excellent resource

This is an excellently put together document, set out clearly and helpful to teachers and pupils, offering an insight and clarification on essays, what the examiners expect with examples and suggestions. Highly recommended.

Matthew S. (Datchworth, GB)
Excellent range of essays

This is so useful for reading essays and actually having feedback directly from the examiners on it. It is also so helpful for identifying topics as well that could be included in the essays. A great read. As a teacher it is invaluable as a resource. Highly recommended.

F. (Oldbury, GB)
Fantastic resource

This is an excellent resource for helping to prepare students for essays. Great for improving teacher knowledge as well as the opportunity for students to mark some examples and see how markschemes are applied. Useful for developing synoptic knowledge in other specifications that don’t have an essay component too.

Daniel H. (Bury St Edmunds, GB)

This resource is so good. As a teacher it has provided me with exemplars when marking the essay but also allowed me to provide better advice to students when completing this style of question.
