Sitting of Assessment Units

June 2018 - AS  Units 1 and 2

June 2018 - A Level Units 1, 2 and 3 (AS exams do not carry forward)


Practical Skills

These are assessed within the written papers, overall at least 15% of the A Level marks account for this. There is no longer coursework (ISA) module. To answer these questions students will have been taught and acquired competence in the appropriate areas of practical skills required by the exam board.

In addition students will need to be awarded a ‘pass’ by their teacher for practical skills mastery. This is a separate endorsement alongside the A Level.  In order to achieve a pass, students will need to have met expectations developed through the explicit acquisition of the technical skills in any practical activity undertaken throughout the course of study. There are 12 practical activities prescribed in the specification which cover the requirements. All of this will be evidenced and centrally stored in school.

Further information

Please select one subject per option block (A, B, C, D and E - listed in Course Title) to ensure there is no clash on your timetable.

By and large most students will follow 3 academic A Levels plus will have the opportunity to add to this with the Extended Project and our Enrichment Programme.

A few students may be able to follow a 4th A Level with advice from our Sixth Form Management team.
