6 Term 4 Preparation for fallback qualifications National 3 Lifeskills Mathematics in S4, National 2 Lifeskills Mathematics units could be banked: Number and Number Processes Shape, Space and Data Money Time Measurement National 4 Mathematics in S4, National 3 Lifeskills Mathematics units could be banked: Shape, Space & Measures Manage Money & Data Numeracy Pupils may be asked to sit the relevant SQA unit tests under formal test conditions. Preparation for fallback qualifications Maths or Lifeskills Maths at National 4 in S4, National 3 Lifeskills Mathematics units could be banked: Shape, Space & Measures Manage Money & Data Numeracy National 5 Mathematics in S4, National 4 Mathematics units should be banked: Numeracy (essential) Expressions and Formulae Relationships Added Value (essential) The fallback position is less clear from National 5 to National 4 because the units are not hierarchical. It is therefore essential that all pupils who are going to attempt National 5 Mathematics sit and pass both the Numeracy and Added Value units at National 4. These are SQA unit tests and will be carried out under formal test conditions.
