Hi Faizal,

you can apply in Banks,LIC's,postals services,SSC,Army,Navy,Civil sevices,ISRO,PSUs etc. These are some of the exams. With a graduation you are eligible to write almost all the government exams.

Join in any good coaching center and start applying for government jobs. Know the pattern of the exam and prepare for it. Concentrate on the topics which you are unable to solve. Practice as many model papers as you can and always have an updated knowledge on Current affairs.

Good Luck!!
