17/1/2017: October/November 2017 IGCSE Biology Grade Thresholds, Syllabus and Past Exam Papers are updated. 16/08/2018 : IGCSE Biology 2018 Past Papers of March and May are updated. 18 January 2019 : October / November 2018 papers are updated. Feb / March and May / June 2019 papers will be updated after result announcements. I was fed up of printing off SATs marking schemes and having about 85 pages to flick through each time I marked a paper, so I’ve put all the answers for each paper onto one page to make it much easier for you to mark.
