i dont know about the highest marks in urdu..Dr Noor ul Ain Fatima&a guy Shafqat Abbas got the highest marks in css 2008...(both marks were equal in urdu)...i could not say anything about my papers before the final result..yes,but i will say that i could not perform well in urdu,but that was because of my own folly...i opted urdu during my graduation and secured 145 marks in it(2nd highest marks in my college)..thatswhy i become overconfident about this subject...and that was a blunder from my side....as far as your second question is concened,i joined Officers Academy,and took regular classes there...sir Sarfraz is really a nice teacher,,,but everybody has his/her own experience..teachers/acsdemies can guide you only..its upto u how you can prepare a subject...dont be confused after opting the urdu,,its not a very very tough subject...
just make a target and then try to achieve it with full zest....open your book and start your preparation now
with all success
