I am studying in M.A third semester(Psychology). I want to appear in the Entrance Exam of UPSC but my General knowledge & English is very weak. I was topper in M.A. first & second sem, the percentage was 85%. I want to join a best UPSC coaching institute anywhere. Please help me out.

Nothing difficult. I have seen even crammers qualifying UPSC. If you can do MA (Psychology), why not UPSC exam? You need to concentrate on some standard general knowledg books as well as on the daily news items and editorials appearing in one or two standard newspapers, as a matter of your routine.
