Diploma

Either you can go for direct second year to the BE in mechanical, automobile, aeronautical stream or you can get a job in private sections as well, and can also prepare for RTO motor inspector exam. Also, you can get a job in ONGC,DRDO ,etc.

No, AICTE and ministry of HRD have banned all engineering programme in distance mode.

If you are doing this Diploma after 10+2 or after 10th but of minimum 3 years and approved by state board of technical education then only you can do it else no. You have to clear 10+2 or any qualification equivalent to that to pursue a graduation programme.

I would suggest you to join any prestigious institute that is offering 3 years Diploma course in computer engineering immediately as the seat are going vacant.
