it was an exceptionable case , as it is very risky as well as lengthy subject. i had completed part one after two and half months with in depth analysis but when i had review the past scores. i am discouraged by it, so my advice is to don't take risk by opting it. because i had seen and met many peoples who had learnt it properly but were unable to get the desired results mostly got numbers in the range of 90-110. so why should one go for a risk when other good option are available to one like us history, public ad, international law, regional languages etc. if you have done average preparation for any regional language you will find yourself in the range of 50's. my cousin even dint able to pronounce some words of Punjabi fluently had scored 54.
