Don't get dejected, rather work hard as much as you can. Insh'allah, one day, you will get through and indeed, ASI job is not an ideal one what Mubashar said. I agree with that, a hard working candidate; having higher capabilities can get an ideal job such as CSS or PCS jobs. Work on your flaws, never ever think to give up and be lion heart, the day will come you will fly your destinations.
