Hello Rahul,

Since I am a lover of news and always have my vigil eyes on the news around the world and also domestic I can answer this with almost honestly.

To be updated with the current affairs most easy way is to get active or be active in social networking sites today news gets posted in social sites faster than news channels. You can follow any current affairs site online if you have an internet connection which is a common thing. Also, you can watch various news channels it may be domestic or international.

If you are fond of reading newspapers you can follow papers. If anyone interested to have better depth knowledge about certain topics or crisis he or she can follow newspapers editorials.

There are many websites which can provide current affairs on a daily basis to your email if you subscribe them like Dainik Jagran etc etc.Many mobile apps are available also.

You can also discuss with the people or friends about any topics and discuss and understand their views which will enhance your capabilities.

If you want to know about defense you can follow defense news websites which will provide news around the world.

You can search in youtube also about international news channels. You can also watch debates in dd news(particularly in India) or any news channels. These are the way through which at least I gather my information about different topics. these are the main places where you can strengthen your current affairs.
