New A level specifications are linear, and AS level qualifications now stand alone and no longer contribute to the final A level grade.
AS levels do not include non-examination assessment. You may decide to study a subject at AS level to demonstrate your abilty to study at this level, to top up your UCAS points, or simply because it's a subject you enjoy.
You can enrol on an AS level with NEC for any of our A levels except for English Literature. If you later decide you want to go on to study for the A level qualification you can do this with NEC.
