This text provides full coverage of the 2001 modular specification requirements. It is an exact match to the specification as the books are structured in the same way as the modules, allowing teachers to follow the specification effectively. The book provides plenty of worked examples showing the key techniques and thousands of questions, along with help for the new coursework element of the specifications. Regular revision opportunities are built in throughout the material and there are practice module tests for each module, written by a senior examiner, to help students build their confidence.
