If you wish to go abroad, then English speaking/Writing/Reading needs to be practiced well. Now you can do that yourself by using open materials on Internet or you can take admission in an English medium school. See its not like that, if you are from the hindi medium school, you can can't go abroad. The thing is if you can't speak english or read english then how will you understand the lectures in the university you will be studying abroad. Also english speaking is required to communicate with the people in the country. So you have to just get the skill of English Speaking/Writing/Reading in whatever way possible. Its not necessary that you have to take admission in english medium school.
