The grade boundaries for the new Edexcel AS Maths and A-level Maths exams taken in May/June 2018 were as follows:

Qualification | A* | A | B | C | D | E |

AS Maths (160) | N/A | 105 | 90 | 75 | 61 | 47 |

66% | 56% | 47% | 38% | 29% | ||

A-Level Maths (300) | 229 | 184 | 155 | 126 | 98 | 70 |

76% | 61% | 52% | 42% | 33% | 23% |

There is of course no guarantee that these will be a good guide to the grade boundaries for the 2019 exams.
