Dear All,
The one & only way by which you can improve upon your English is practice, practice & practice again. To start with, you find it very annoying & even embarrassing to stumble without proper vocabulary, half completed sentences (They refer to as Butler English) and so on.
Never feel ashamed to come up and converse whatever you think. Things to avoid,
* Being Shy
* Fear within
* And finally, care a damn about what other think!!!
When you want to succeed in your initiative, be bold and start crossing obstacles as they come.
Before I conclude, it is also advisory to take a list of GMAT word list, start 5 words a day, and practice the same by framing it in sentences in your day-to-day life. This will definitely give an edge over others.
"After all, there is no end for learning process"
Good Luck,
