Resources designed to support learners of the new next generation BTEC First in Applied Science: Principles of Applied Science specification*.   This Revision Guide has been specifically written for externally assessed Unit 1: Principles of science in Award 1 of the Level 2 BTEC Firsts in Applied Science. The guide is organised by the assessment structure of the qualification and gives students guidance on the external assessment. Key point summaries of what candidates should know are included to reinforce teaching. Information is presented in a straightforward, user-friendly way. Worked examples, exam questions, revision practice questions and ''test yourself'' diagnostic questions prepare students for the exams ahead. In addition, the Revision Guide provides students with all the answers to all the questions in the book.   * From 2012, Pearson’s BTEC First qualifications have been under re-development, so schools and colleges could be teaching the existing 2010 specification or the new next generation 2012-2013 specification. There are different Student Books to support each specification. If learners are unsure, they should check with their teacher or tutor.
