Hi Anirudha,

The candidates who have passed class 10th or 12th can apply for admission to Diploma in Engineering .

But, as you've already completed your +2, it will be my advice to apply directly for a B. Tech instead of a Diploma.

Anyhow, after completing a degree in Diploma, you can go for B. Tech which will collectively take 6 years to complete your engineering (3 years diploma + 3 years B. Tech)

Hope this was helpful.
