how to increase the level of understanding in rc in cat exam

Hi Deep, the sustainable solution to is that you should read a lot because when we read a lot our ability to pick up the tone, the general idea etc increases.

Books are generally a good option. If you do not have a habit of reading then you should start by picking up any book you like.

Once you develop an interest in reading and read more understanding RCs will be easier.

Hope this helps!
