Students need to learn the exact trigonometric values for 0 o, 30 o, 45 o, 60 o and 90 o (or how to be able to quickly recall these using a diagram and Pythagoras, which is easier!). PROBABILITY New Topic Paper / Ques. No. Performance and Action Points Venn diagrams and Set 3H Q1 This question involved a Venn diagram and Notation understanding set notation. The most common score for this question was two-thirds of the total marks. Action Points: Students must not forget to write all the remaining numbers in the universal set (a common error). Ensure that students know marks are lost when labels are not used. Students should know that examiners report the students who perform best tick off all the potential values when completing a Venn diagram. Disclaimer All efforts have been made to represent, accurately, the feedback provided by Edexcel1,2. Edexcel’s examiner’s reports included points of consideration for exam centres, some of which have been included as the bulleted action points above, whilst some of the action points represented here are the views of the author.
