Dear Aspirant,

It all depends on which government job you want to pursue. If you want to  go civil services, or UPSC exam, you only need to have graduation that may be in arts, science or commerce. But if you want to teach, then you have to pursue graduation in that particular subject. In case of diploma, there are very less chances of getting recruited at central level government job by only having diploma. But, if we talk about good diploma's, you can go for computer diploma like DCA(Diploma in Computer Applications) or Computer typing. I would suggest you to complete your graduation and you can go with Diploma side by side too. Rest is your call. Choose wisely.

Hope this helped in resolving your query.

All the Best!!
