Dear Bibhu,

Start reading newspapers- The Hindu, Indian Express, Economic times. That will not only help you in improving vocabulary but also aquaint you with current affairs which will later be beneficial to you. Apart from that buy this book 'word power made easy' by Normal Lewis, that's a really helpful book.  And there is an app called 'pocket' download that and read one article daily.

Apart from this, keep solving mock test and sectional tests on daily basis. And this will be sufficient.

All the best. Thank you.
