PAPER 3
Paper 3 will be a timetabled, laboratory-based practical paper focussing on
the following experimental skills:
• manipulation of apparatus;
• presentation of data;
• analysis and evaluation.
The paper:
• will consist of two or more questions,
• will consist of two approximately equal halves so that Centres can provide
microscopes for half of the candidates at a time,
• will include an experiment or experiments requiring candidates to collect
quantitative or qualitative data, to draw up tables, charts, graphs and other
appropriate means of presenting the data and to analyse it to draw appropriate
conclusions,
• will require candidates to make observations of specimens, to display
their observations appropriately and to make appropriate analyses, including
making calculations, deductions and conclusions from the observations,
• will include questions set in different areas of AS Biology, and may include
material from unfamiliar contexts (see above).
Each examination session, two versions of Paper 3 will be available, Paper A
and Paper B. Each candidate should take one of these two papers. Some
Centres may wish to divide their candidates so that some are entered for Paper
A and the others are entered for the Paper B; other Centres may wish to enter all
of their candidates for the same paper. Paper A and Paper B will contain
different questions, but will be equivalent in the skills assessed and in the level of
demand.
