A friend, whose daughter is doing her GCSE in this syllabus, has asked me to give her some extra support in preparation for the higher level terminal exam this June. While I have used the textbooks, I have never taught the syllabus and I am finding difficulties understanding the assessment scheme. I wonder if a teacher familiar with the scheme can help. From the specification document my understanding is 50% of the marks are allocated to the terminal exam which is in two equal parts - non calculator and calculator. The other 50% is gained from module exams. Ten modules are available, M1 (G grade standard) to M10 (A* standard). Each module is divided equally into a non-calculator and calculator part. Modules can be sat in January, March and June over Y10 & Y11. Each module can be repeated once prior to certification. Students (candidates!) would normally enter three appropriate modules the best two would be chosen for final grade. Here's where I get lost! How are the best two modules chosen if the candidate has attempted more than two modules over two years? For example if a candidate gains the (hypothetical) raw marks listed below, which two modules would be chosen and what overall grade might be awarded? M7: 73%; M8: 71%; M9: 66%; Terminal Higher Level: 68%.
