Psychology book to cover whole CSS syllabus
 

Is there any single book which can cover whole of most part of new Psychology syllabus in a way that no other book is required. (Of course internet resources can be used to get better understanding and read any missing topic) but generally the book should cover whole syllabus... Need urgent recommendations.

I don't think there is any book that covers the whole syllabus absolutely... you'll have to help yourself with topics like forensic psychology

Most commonly recommended books cover all but two topics: organizational/industrial psychology and forensic psychology. For them you will have to look elsewhere.

The recommended books are:
1. Understanding Psychology by Feldman 10th or later edition
2. Psychology by Ciccarelli 3rd edition
3. Psychology Themes and Variations by Wayne Weiten 9th edition
Definitely get Feldman since it will get you acquainted with the field in no time. Out of the rest of the two, I would suggest get e-books of both of them, or at least of Weiten's book (since it offers some additional things as well as the same issues as Feldman, but in a different manner).

But I would suggest that you should go through "Theories of Personality" by Schultz and Schultz (10th edition). It will help a lot with personality, motivation, learning etc.
Furthermore, "Developmental Psychology" by Shaffer and Kipp (8th edition) is another excellent book to go through if you have time.
