Mathematics J560,04 Higher November 2022
The mark scheme document provides detailed guidance on how marks are awarded for each question in the November 2022 GCSE Mathematics J560/04 Paper 4 (Higher Tier). Key aspects include:
1. Marking Criteria and Instructions – Explanation of M (method), A (accuracy), B (independent), and SC (special case) marks; handling misreads, transcription errors, and contradictory responses.
2. Standard Form and LCM Calculation – Converting numbers to standard form; determining the least common multiple using factorization and listing multiples.
3. Probability and Statistics – Calculating probability from a Venn diagram; interpreting cumulative frequency graphs; comparing distributions using median and interquartile range.
4. Algebra and Geometry – Solving quadratic equations using factorization and completing the square; proving similarity of triangles; finding the equation of a tangent to a circle.
5. Financial and Percentage Calculations – Calculating percentage increase/decrease; predicting population growth using exponential models; determining best value for money among different product sizes.
6. Trigonometry and Coordinate Geometry – Using the cosine rule to find missing sides in triangles; describing transformations of graphs; solving systems of equations algebraically.
