B.A Mechanics

Hello Mukesh Kumar, you have indeed raised a very interesting query. In India at least at the moment admissions to any graduation course is based on the marks obtained in 12th examination. Diploma holders do not do their 12th hence they have used problem on their hands. However many states have declared Diploma courses as equivalent to 12th examination. You just need to approach the administrative staff of the institute from where you did your Diploma and get the requisite equivalent Certificate. Once you apply in this then you can go in for graduation in any subject of your desire. Best wishes to you.
