let me explain you...To understand English first you have to grip vocabulary section... for this the best way is reading...u can start with magazine champak or tell me why..these two magazines are lucid and also interesting... after a few months u can read a English news paper.... strongly I recommend the Hindu or the Indian express. just read it blindly 2 or 3 months...u will surely find a change in yourself.. for vocab section u can read word power made easy by Norman Lewis. just do these things and notice difference.
