How has the mark scheme changed?

• It has been simplified to make it easier for centres and candidates to understand
• The generic part of the mark scheme which applies to Q1(c) and Q2-5(b) has been moved into Table 1 and the generic part of the mark scheme which applies to Q2-5(c) can be found in Table 2.
• Changes to the distribution of marks in some of the bands in the levels include:
o the removal of overlapping marks
o the formal recognition of developed explanations that are already given by many candidates.
o L3 in Q1d now starts at 4 marks.
o There are now 2 marks available in L5 for evaluation in optional Part c questions.
