The fact that you are asking could be that you are not comfortable lying. Jut be proud of who you are and yes, you should write about what makes YOU special, not everyone knows Urdu. I am sure that you have many qualities that you can bring to the table besides grades and test scores. The minute that you start writing how to beat the system you will not only be lying but you will get sidetracked of all the amazing things that you can write about yourself. Good luck!
