Directly confirmed against the official PDF: linear qualification, two externally-assessed, untiered written papers taken in the same series. Paper 1 (2h, 110 marks, 61.1%) assesses only core (non-bold-referenced) content; Paper 2 (1h15, 70 marks, 38.9%) assesses all content including bold-referenced material – the identical assessment-weighting pattern used across Pearson's International GCSE sciences suite (matches sibling Biology 4BI1 and Physics 4PH1, independently re-confirmed from 4CH1's own source PDF). First teaching September 2017, first assessment June 2019.
