DS is worried that he might not do well enough in his (second attempt) at AQA Physics AS ISA (the practical/investigative test) to give him a good overall score at AS level. The ISA is also known as Unit 3.
Does anyone know if it's possible to re-sit the ISA unit of the AS exam in the second (A2 year) of study, along with A2s (ie not repeating the AS apart from the ISA)?
Perhaps he's unnecessarily worried (no results yet) but he'd like his mind set at rest! Thanks.
