Dear Student ,

As per your profile suggests that you're an Engineering aspirant , So, in that case you should know that the course duration for Engineering is 4 years .

Well, after 12th , if you want to pursue normal degree/ diploma , you need min 3 years to complete the course as per the course duration.

If you're interested to get a job quickly , you can pursue a course from Industrial Training Institute (mostly known as ITI) .

You can check more about ITI courses from here :
