Dear Aspirant,

to avail good marks motivation and determination is very essential apart from that you must take help of good books and practice well. One of the highly recommended book is NCC Hand Book of R Gupta’s .

Usually the papers are not the same as the previous years paper but sometimes might be similar, hence solving previous years question papers is a good way to study.

To get access to some of the model papers and previous years papers, you can search them online.
