Advanced physics is a two year course split into two parts. In the first year, students cover the AS units, outlined below, and then sit the corresponding AS examination. This constitutes the foundation assessment of the Advanced level course. Successful candidates then have the option to continue their studies for a further year to gain the full Advanced level qualification, subject to the final A2 examination at the end of the second year, or may choose to leave the course at this point and be certified at AS level.
