      AS and A Level Mathematics A and B 03 April 2018

      AS and A Level Mathematics A and B

      The sample assessment materials for AS and A Level Mathematics A (H230/H240) and AS and A Level Mathematics B (MEI) (H630/H640) have been amended to correct some minor mistakes. The updated versions can be found on the qualification pages (linked below), within the 'Assessment' section. The following changes were made:

      Rubrics

      • Minor changes made to wording.

      Formulae

      • For all four qualifications (H230, H240, H630, H640) the nCr form has been added for Binomial Series.
      • For the two A Level qualifications (H240 and H640) the value z = 2.575 has been corrected to 2.576 in the table of percentage points of the Normal distribution.

      Other amendments to individual question papers:

      • H230/01: The mark scheme for question 10(iii) has been updated to reflect changes made to the question during accreditation.
      • H230/02: In question 5(ii) the value of p has been corrected to 320 and the interval of accepted values to [300,400].
      • H230/02: The assessment objective grid on page 12 of the mark scheme has no row for 10(iv). This has now been inserted.
      • H240/02: In the mark scheme for question 10, x has been corrected to x̄ three times.
      • H640/02: In the question paper on page 10 the boxes have been corrected to show all of the intended text.

      We apologise for the inconvenience caused. Please make sure you are using the most up-to-date version of the materials with your students.
