Revision Preparation Powerpoint File. Perfect for teachers to use in lessons on the IWB or to share with students to make their own effective revision resources. There are hundred of slides I have collated by sub topic area on powerpoint. Topics 1-4 covered. This file will be suitable for teachers and students taking paper 1, AQA 7402 or those taking both AS papers 7401. Sections are organised bytopic and subtopic where appropriate and contain past paper question/mark scheme, keyword and digrams from kerboodle and summary sheets. I hope you get lots of use and increased confidence for upcoming exams.
