Paper 2 : 2¼ h 36% of total Section A (about ¾ h) One data based question and several short answer questions, all compulsory. Section B (about 1½ h) Two extended response questions from a choice of four questions. Paper 3 : 1¼ h 20% of totalSeveral short answer or structured questions and one extended response question in each of the optional topics Internal Assessment 24% of total Assessed by the teacher. More detail will be given later. N.B. Calculators are not allowed for Paper 1. Calculators are needed for Paper 2 and Paper 3. Programmable/Graphic calculators are allowed. |
