You can pursue a diploma in commercial arts on the basis of your SSC. But getting a degree on the basis of diploma in mechanical engineering is not possible.

Diploma in computer will give you practical exposure which you will lack while pursuing 11th and 12th and your studies will be more subject specific. The other benefit that you will have that if you wish to pursue engineering after diploma, you can take direct admission in the second year of engineering.

Hi Joyita,
Maybe, you could do a B.Arch, or maybe an interior design course or any other allied field courses.

Hi Rohan,
A minimum of 80/200 makes you eligible to take up Architecture course, I would suggest a score of 100/200 will get you a good college with 67% in Dip.

Go for B.Tech in mechanical or automobile.

After polytechnic, you can do B.Tech, BE & BBA.
