Well it is not wrong at all. But as far as my experience is concerned its positive because for the preparation I just went to the world times academy and why I went there because I have been reading jahangirs world times monthly magazine for last 2 years. I had the same confusion in my mind regarding CSS coaching academies but I had to change my opinion because at world times academy they clearly mentioned the names who studied their and then qualified the exam and also told that rest of them were just interviewed by the jwt magazine after their success in CSS. So my opinion is slightly different.
