Maths GCSE 150 questions, solutions and answers to be written

I am seeking a highly skilled mathematics writer to author 150 standardised test questions, with accompanying step-by-step solutions and answers, for General Certificate of Secondary Education (GCSE) level mathematics. The questions must be tailored to the GCSE curriculum and representative of the varying difficulty levels found on the examination. It must be written in British English.

For each problem, the freelancer will provide a clearly written question stem followed by a fully worked out solution showing the mathematical reasoning and calculations required to arrive at the correct response. Answers should be presented in a straightforward format. Graphs, diagrams or other visual aids may be incorporated where applicable. The overarching goal is to simulate actual practice problems and help students strengthen their understanding of core maths concepts.

This initial set of 150 practice items will serve as a sample of the freelancer's expertise and abilities. Topical coverage, question/solution quality, and presentation style will be evaluated. If the trial is deemed successful based on these criteria, there may be an opportunity for a follow-up project involving 1,000 additional questions tailored for GCSE maths exam preparation. Expertise in curriculum standards, strong technical abilities, and careful proofreading skills are essential to complete this work to a high standard. Eligible freelancers should have extensive experience creating mathematics content at the GCSE level or above.
