I noticed my daughter struggles with arithmetic. I was surprised to learn that IGCSE Maths allows the use of a calculator in both papers. Might be a consideration when I decide whether to let her to IGCSE or GCSE Maths. IGCSE Maths has been known as the more difficult paper because they have to learn more topics than those doing GCSE Maths. I suppose since my daughter does struggle a bit with Maths either way, it will not be an easy choice anyway.
