OCR AS Mathematics Student Unit Guide: Module 4721 Core Maths 1

Summary:
Student Unit Guides are perfect for revision. Each guide is written by an examiner and explains the unit requirements, summarises the relevant unit content and includes a series of specimen questions and answers.

There are three sections to each guide:

Introduction – includes advice on how to use the guide, an explanation of the skills being tested by the assessment objectives, an outline of the unit or module and, depending on the unit, suggestions for how to revise effectively and prepare for the examination questions.

Content Guidance – provides an examiner’s overview of the module’s key terms and concepts and identifies opportunities to exhibit the skills required by the unit. It is designed to help students to structure their revision and make them aware of the concepts they need to understand the exam and how they might analyse and evaluate topics.

Question and Answers – sample questions and with graded answers which have been carefully written to reflect the style of the unit. All responses are accompanied by commentaries which highlight their respective strengths and weaknesses, giving students an insight into the mind of the examiner.

• A revision guide specifically written to meet the requirements of the unit
  

• Written by an examiner with commentary on key points and concepts 
  

• Features specimen questions and answers, together with examiner's comments
