walikum us salam
advice which i can give to you is that you should search for the good books, do tell me i will suggest you , after that you should prepare from that and revise again and again, also read newspaper regularly, and write essay's
i think this would be enough and there is no need to join any academy as i think academy can only give tips, but if you develop the reading habbit then you can learn easily, academies are just waste of time because every tip is present at cssforum..
