Length of Course

Five full days, 40 hours total.

The purpose of the course is to provide students with a concise revision of the exam theory required to meet the demands of the A level qualification, together with advice on examination technique specific to the AQA A level examinations.

The time allocated to a unit for the content will involve revision of key points of each topic within that unit, with illustrations of how that subject matter may be examined in the unit examination. The half day allocated for examination technique and practice will be used to look at identifying the requirements of questions and applying the theory learned to the questions, to maximise marks.
