GCSE Maths questions

We are a new Mobile App for GCSE students to study and take quizzes to improve their Maths skills. We need an initial set of GCSE-approved Maths questions for our App. We therefore require a content writer to create 966 Maths questions (with answers) ideally to be delivered in an Excel or CSV file. The questions need to follow the GCSE AQA maths specification.
These are the 6 Main Topics:
1. Number – 8 subtopics
2. Algebra – 11 subtopics
3. Ratio, Proportion and rate of change – 8 subtopics
4. Geometry and Measures – 12 subtopics
5. Probability – 4 subtopics
6. Statistics – 3 subtopics
I have attached a link to the specification below, and the questions need to be in line to the specification. Out of the 46 subtopics, there needs to be 21 questions created for each subtopic; 966 questions in total. the questions need to be provided in a fairly equal split between 2 different question types.

Question type 1: Written question, four answers provided with one being correct (multiple choice)
Question type 2: Written question, one answer provided
