To achieve grades 5-7, candidates will be able to:
demonstrate largely accurate and appropriate astronomical knowledge and understanding, using largely accurate astronomical terminology and use it to largely accurately explain ideas and concepts in a range of familiar and unfamiliar contexts
in relation to observations, make accurate predictions, suggest hypotheses or plan feasible observations to test them
use mathematics to perform a range of multi-step calculations
analyse qualitative and quantitative data to draw accurate conclusions supported by a range of evidence
evaluate methodologies to suggest improvements to observational methods, and comment on astronomical conclusions.
To achieve grades 8-9, candidates will be able to:
demonstrate relevant and comprehensive astronomical knowledge and understanding, using accurate astronomical terminology, and use it to explain ideas and concepts in familiar and unfamiliar contexts
in relation to observations, make accurate predictions, suggest valid hypotheses or plan viable observations to test them
use a range of mathematical skills to solve complex astronomical problems
critically analyse qualitative and quantitative data to draw logical conclusions that are clearly supported by evidence
critically evaluate and refine observational methodologies, and judge the validity of astronomical conclusions.
This is a question with example answers that would be equivalent to grades 2, 5 and 9 respectively. Look carefully at the question, the answers and the examiner's comments to help you judge what makes a great answer. You can see the paper that this question was taken from, along with further examiners' commentary on other questions here.
