Advice, if I may. I will not quote the question directly or say what topic it is just yet - I am aware we need to wait 24 hours before the end of the exam before discussing. However - this question has riled me greatly - more so than any other question from any other year. I could teach it to my 10 year old son who would be able to do it easily. However, I did not teach this topic to my foundation class as Edexcel ruled it out in their specification. They mentioned the new syllabus addition to foundation content in their specification and then made the statement this particular style of question is not examined in the foundation paper. Am I wrong with my thoughts? Much appreciate the advice.
