They may wish to include detailed knowledge of topics from any of the AS and AH units. They may also gain credit for including material which stems from wider reading and reflects greater depth of knowledge. The choice of material to include lies entirely with the student.
How Science Works is n integral part of the specification and, while not being specifically tested in the essay, will certainly gain credit if relevant. The maximum number of marks that can be awarded is: Scientific content Breadth of knowledge Relevance Quality of Written Communication Total 16 3 25 This means that the examiner is looking for; evidence of knowledge and understanding in keeping with an A level course of study, selection of material relevant to the title, and drawn from different areas of the specification, the ability to resent an argument coherently and logically, using appropriate biological language.
