Dear
Unless you start trying you will not learn. To attempt is the key, May be you will speak wrong But try with helpfull friends.
a). Read Economic Times Daily
b). Listen English news daily.
c). Watch english movies with english captions.
b). Read and speak in front of mirror daily for ten minutes.
c). Donot over emphasis on increasing vocabulary it will increase naturally.
d). Try to right paragraph daily on any topic start from easier one
Finally most importantly try to interact with people in english, In your locality there must be some english speaking school. Do not join them for theoretical part, It will not help
Join their practice time batch, there you will find many people like you and by practicing you will learn new worlds and start owning words gradually . One day that stage will come when you will not have to try . english will come automatically from you.
