Hi Shanmugaraja,

A number of resources are available in the market, both in print as well as online. Since RRB exam 2016 is in the online format, I suggest you to try to do as much of your preparation as possible online. This will help you get accustomed to the exam environment and patter.

Cracku provides a number of online courses, both premium and free.
