AOA genius minds
Since i am in the business of CSS one thing stuck my mind that y should one go CSS

while just after getting masters degree one can acquire the post of AM and SPS 08 and in reasonable period of time one can move to SPS-11

Are there any special privileges that are given to CSS, what are they?

and what should be chosen between a job on CSS basis and a job on CA basis?

My questions may seem funny to you people
but i really wanna get answers to these questions froms knowledgeable persons

I am looking forward and waiting for the guidance from you people

and would be really thankful to you people

Regards
Sara
