This book is divided into two sections. In the first section, the entire syllabus for Part-A of CSIR-UGC-NET examination has been covered. All the previous year questions have been segregated topic wise and given after every topic, so that students get to know the importance of every topic and with reference to the type of questions asked. In the second section all the previous year solved papers are given from December 2012 to June 2019 of all the streams i.e. Life Sciences, Physical Sciences, Chemical Sciences, Earth Sciences, Mathematical Sciences. A great care has been taken keeping in mind the varied backgrounds of the students and how they perceive maths to be, most of the questions have been solved logically without using any complex calculation or difficult maths formulae.
