Hy Raj!

Some good ideas to improve your English skills without a professional teacher are:

*Buy a beginner's edition of a grammatic book
*Read as much as possible
*Watch as many dvds as possible (in English maybe with subtitles in your first language...be creative)
*Listen to songs in English together with the lyrics
*Start with the easy stuff and then go more and more into detail
*Make sure you are aware of the rules and how to use it before taking up anything new

I hope this helps you. Good luck and hold your head up high.
