    Why don't you think stem and leaf can appear on a calculator paper? Not every topic on a calc paper requires a calc - most don't.

    The CGP revision and practice workbook is fine and is available from all high street and online book sellers.
    I like the edexcel separate revision guide and practice workbooks that you can buy online eg Amazon.co.uk or bookdepository.com
