First of all try to build up your English vocabulary. So always write in English, instead of using & taking support of Roman English. Also search to find good English friends from the plate form of Language Exchange of italki.com. Read simple English story books & also listen to English News on Radio & TV. Slow speed English News from BBC is also very helpful for you. Same time you may take regular classes of English, with a On-line English Community Teacher of italki.com.

I would recommend using a kindle (or the kindle software) or another e-reader that supports dictionaries. With this, you can read a book, and when you come across a word, you can quickly and easily find out its meaning. Generally speaking, I would also recommend setting yourself a fixed schedule. If you get into the routine of seeing, hearing or speaking English every day, you'll learn a lot faster.

Read books. Most of the contemporary ones are easy read.
