Bhawna, I suggest that you prepare and give state PSC exams. Also keep reading the weekly Rojgar samachar (Employment newspaper) and find out about applying to various Govt sector jobs / vaccancies / exams. In the meantime if you can do then try to go for post graduation in a subject of your choice.
