• Develop a deeper appreciation of the skills, knowledge and understanding of How Science Works.
• Develop essential knowledge and understanding of different areas of the subject and how they relate to each other.

Course content

The AS course consists of three modules.

Entry requirements

See the school offering the course.


The course is delivered through the medium of Welsh. During the AS
course there are two written examinations (CH1 – 40%, CH2 – 40%). The
CH3 module consists of internally assessed practical tasks, and
contributes 20% to the overall mark.
For the full A2 qualification, the AS modules contribute to the final grade
(CH1 – 20%, CH2 – 20%, CH3 – 10%). There are two additional modules
that are assessed through examination (CH4 – 20%, CH5 – 20%) and a
further assessment of practical skills (CH6 – 10%).

Future opportunities

The minimum requirement for access to these courses is at least a ‘C’
grade in GCSE Core and Additional Science and at least a grade B in GCSE
Mathematics. A good grade in Chemistry Advanced Subsidiary opens a
number of doors, and a good grade in the full A level is essential for some
university courses such as Medicine, Dentistry and Veterinary Science.
