Dear Asif,
I hope you are doing fine. It is a pleasure to see you around. Sorry for the delayed response because I am quite busy these days with things and issue around. Now lets get to your queries:
I request you to please check my case carefully. It's nothing usual sir. And then suggest me whether I'll be accepted in normal lot or disabiled lot. Please be straight. I erased the meaning of 'hard-feelings' from my dictionary long back.
You have been in touch with me personally for quite sometime and you must realize one thing that I never tend to mislead somebody so you better do not worry about this issue. Now lets get to other issue.
Given my eyesight - which is extremely bad - should I opt for disability quota?
To best of my knowledge, if Nystagmus in severe conditions can impair normal functions of day to day life and in your case, you appear doing things quite normal so it makes you eligible for the exams. Now it is upto the decision of board if they are going to declare you disable or not. So at the moment, you must not worry about it. Believe in your self, do the exceptional and you will be rewarded.
Here, I would like to quote the example of my fellow Commoner Saima Saleem, she did it, did it with honors and she got allocated to group of her choice that is Foreign Services of Pakistan. All I would say that you better prepare well and rest leave everything to Allah.
Now I comming to the description of disability in rules and regulation governing medical fitness of candidates. The
Annes B of CSS Rules issued by Federal Public Service Commission in 2008 has provided us specifics for occupational groups like Police and Railways and to best of my knowledge you are not fit for both.
About other groups, since I don't know your eye sight specifics I can say. Please have a look at the
Eyes sight Requirement for CSS Pakistan here and you will get the answer.
In case you are below the range they consider normal, still you have Commerce and Trade Group, Pakistan Audit and Accounts group, Information group and Postal. Not only this but in case you get to some exceptional position like CSS 2007 qualifier Saima Saleem, you can end up with something exceptional on the similar grounds.
Lastly, I would say, give it a strong blow and you will find, the impossible will turn possible. I wish you all the very best.
