Some other salient features of the series are as follows: • Concepts have been highlighted to make them stand out on the printed page. • Tips to write correctly and alerts to avoid common errors have also been highlighted. Both teachers and students will find these tips extremely useful. • There are review sections to evaluate learning outcome. • Exercises are sufficiently large in number and well-graded. There is also a great deal of variety in them, for they include crossword puzzles, word searches, riddles, etc. • Exercises have been designed to generate positivity among students and to inculcate ethical values in them without their being conscious of it. We have a two fold aim in the section dealing with composition: students should be able to use their imagination and organise their thoughts. Illustrative material provided by us as well as the exercises listed for the students should help in the realisation of this aim. Texts for listening comprehension are available online and can be accessed at www.sultan-chand.com/eegc4/main.html. Besides, grammar practice exercises in an interactive format and additional study material to improve writing skills are also available online. For the convenience of the students, listening texts have also been given at the end of the book. Worksheets for additional practice are available at www.sultan-chand.com/ws.
