How to increase general knowledge?
There are many ways available for improving general knowledge some of them are,Read general knowledge books, read news papers in English as well as Telugu. GK apps are available in playstore try to download and use it.participate in quiz competitions. Attend for seminars and conference as well.
A newspaper is a very essential source for government competition preparation because they use the latest affairs to test a candidate's present knowledge. I also suggest that instead of purchasing different newspapers, try finding a suitable internet portal on what you can find the latest pieces of information.
I think you should refer different newspapers. My suggestion is " The Hindu " is perfect for gaining knowledge and also for the preparation of different competative examinations .
