Further Maths MEI B optionsWatch
Where learners take more than the required number of papers, the combination of papers that result in the best grade will be used.
Note, however, that only certain combinations of papers are allowed. So if you were to take, say, Mechanics Major + Statistics Minor + Modelling with Algorithms, then the allowed combinations are Mech Major + Stats minor, and Mech Major + MWA. So Mech Major will always count towards your final result. Therefore, from a grade-maximising perspective, it may be optimal to take 4 minor papers, since then your worst paper is always dropped.
Note also section 2B of the specification:
Learners may not enter for Mechanics Major (Y421) and Mechanics Minor (Y431).
Learners may not enter for Statistics Major (Y422) and Statistics Minor (Y432).
