This subject report is listed under Biology in the 2015 examination archive. The catalogue session is May 2015. The information below helps you identify the document before opening the complete PDF. Subject, year and session labels come from the archive catalogue; the original cover remains the reference if a label differs. A file is not automatically suitable for your current syllabus simply because its subject name matches.
For coursework research, read this document as a reference rather than a template to submit. Notice how the question, evidence and explanation connect. If a paired commentary or subject report is available, compare it with the original work instead of assuming a polished essay received a particular mark. Historical examples may belong to an earlier assessment framework.
The public preview contains file information and, where reliable text extraction is available, a limited opening excerpt.

The range and suitability of the work submitted
In this session essays were submitted in a wide range of appropriate topics including
microbiology, fact ors affecting germination and growth of seedlings, biochemical
investigations, molecular genetics, behavioural studies in invertebrates, fish and mammals, a
variety of human biology topics (including behaviour, memory, perception of stimuli, and
nutrition), studies based on a particular disease and ecological studies based on particular
local phenomena or environmental issues.
Topics that do not have a strong biological basis such as ethical issues related to particular
kinds of research, different approac hes to medicine, surveys of attitudes to biological issues
or the treatment of biological issues in the media rarely lead to successful essays.
Coordinators and supervisors should be aware of the particular problems related to essay s
dealing with the impact of a particular diet or of consumer products such as caffeine, coffee,
energy drinks, and vitamin supplements on athletic performance and/or memory. Many of
these studies rely on small sample sizes and short time frames and are therefore unlikely to
lead to meaningful outcomes. Students should also steer clear of topics such as creationism,
intelligent design, personal injuries and alternative medicines.
Essays based on practical work carried out at a university or other research institution, have
become less common but continue to be submitted. The current guide makes it very clear that
essays of this type must be accompanied by a covering letter from a qualified person at the
external institution but examiners continue to report that in many of cases, this requirement is
not met. A cover letter should outline the role of the candidate in deciding the research
approach as well as the type and extent of guidance provided at the institution. Clear
evidence must be provided (in the form of a covering letter ), that the candidate has had a
sufficient level of input into decisions about the research
