Core Science Prediction Papers - Higher - 2016 - Biology, Chemistry & Physics AQA Prediction papers based on previous examination questions. There are 50 mark per paper (1 hour). Question based on past papers but re-written for the purpose of the exam. They are designed to get students to revise the key topics that are more likely to appear in the 2016 exam. Paper come with mark scheme and so can be set as a class task, homework or revision task. Foundation tier also available.

This paper consists of new questions that have been designed around previous examinations. The assessment is produced after mapping questions from previous years. This includes a mark scheme as a separate document. Great for revision and discussion.

Due to a number of requests these are some more assessment papers for additional biology, chemistry and physics. These are 3 60 minute assessments that are made up of new questions from the additional science programme of study. These help students with revision and preparation for examination. Really good when students have done all of the past papers already. These are DIFFERENT to the predicted papers that are available separately.

A range of revision activities for KS3 Can be used as starters, plenaries, homework and/or for independent revision.
