Hello Dear

It is sad but I would say you are a bit frustrated by the situation. Don't blame anyone for your failure.In the end it is one's efforts and luck that determine the success.may be you were not destined to achieve it tis time, but keep your spirits high and go for next time.

As for as corruption is concerned ,I suggest, don't contaminate your mind with such baseless ideas.At least CSS is the exam beyond any corruption .The proof is all those successful people who passed it purely on the basis of MERIT.I know many so do you.

We should trust our institutions .All are not corrupt.this is the way we can move ahead.

Best Regards
