SUMMARY OF ASSESSMENT
This specification is divided into a total of 6 units, 3 AS units and 3 A level units. Weightings noted below are expressed in terms of the full A level qualification. Marks are given as raw and uniform marks (UM).

AS (3 units)
Biology 1
20 % 1 hour 30 min Written Paper 70 marks (120UM)
Unit title Basic Biochemistry and cell organisation
Outline of paper structure
– Short and longer structured questions, choice of 1 from 2 essays. Biology 2
20 % 1 hour 30 min Written Paper 70 marks (120UM)
Unit Title Biodiversity and physiology of Body Systems
Outline of paper structure
– Short and longer structured questions, choice of 1 from 2 essays. Biology 3
10 % Internal assessment 44 marks (60UM)
AS Unit AS Practical assessment
Experimental work set in centre, completed by candidates over 3 month period. Marked by board plus, low power plan microscope drawing.

A LEVEL (the above plus a further 3 units)
Biology 4
20 % 1 hour 45 min Written Paper 80 marks (120UM)
Unit title Metabolism, Microbiology and Homeostasis
Outline of paper structure
– Short and longer structured questions, choice of 1 from 2 essays. Small % synoptic marks.
Biology 5
20 % 1 hour 45 min Written Paper 80 marks (120UM)
Unit title Environment, Genetics and Evolution
Outline of paper structure
– Short and longer structured questions, choice of 1 from 2 essays. Small % synoptic marks.
Biology 6
10 % Internal assessment 50 marks (60UM)
A level Unit AL Practical assessment
Experimental work set in centre, completed by candidates over 3 month period. Marked by board plus one microscope drawing and calibration. Assessment units BY1, BY2 and BY4 are available in January. All assessment units are available in June.

Synoptic aspects are assessed by a few marks in assessments for units BY 4, BY 5. Practical work, BY6 is considered to be inherently synoptic. One theory unit at AS (BY2) and one at A2 (BY4) is a Biology/Human Biology option. One unit at each of AS and A2 is common to both courses along with the practical assessments. Candidates’ choice of units will determine whether they obtain a qualification in either Biology or Human Biology.
