Pardon me if I sound retard ..
But usage of English in our educational system is making things difficult for some students . Not all students can work well in english and not everyone can make up their mind to understand those new words of this language.
In our country, there are many people who have very high iq and have got a very sound mind still cannot go ahead in education if they don't have a complete grasp on english or regard education as difficult cause of new language.
Your native language affects your brain development. Western nations have the benefit that they use english in their daily life also then carry studying in the same language and also rule the world with this same language.
While it's not case with us, our mind is developed in urdu , study in Same language but then told that it's important to learn English to move ahead or to become a successful person in this earth like the famous people. In order to get a job , you need to have grasp in english that is just a injustice to those who don't know english.
Seems like your iq is not any benefit to you unless you learn English . It should be limited to a language of interaction and should not be given the state of dependency on it .
