The Pearson CSAT Manual 2012 is created by collating inputs from both extensive research and intense learning. The manual is modeled as per the latest syllabus of the Indian Civil Services (Preliminary) Examination and lays stress, especially, on those topics from which questions will be majorly asked. This manual owes its existence to years of research, scientific and logical planning. The text is presented in a scientific manner to help the candidate learn, understand, and retain information for a longer period of time. A number of detailed tables and illustrations support the concepts explained. One of the unique features of this manual is the extra material provided in the margins.
