i know that how to improve english and sentence structure so don't give me lecture of english.If any one want to improve his english.They read dawn news and any of other article and write its in own word.It automatically improve his english.If it is only exam of english then i didn't considered this exam if you people want to debate with me only on engish not on knowing any thing about their respective field.It is better for you people to leave study.I didn't discourage anyone to leave css.If anyone attempt css.They must given this exam.But their checking policy is not transparent.It is foreign language so i didn't give importance to language.Knowledge will make you different from other people not english.
