Dear mayank, 

As you say,  you are completed the diploma in information technology, then you wanted to do B. E. 

So you can apply for only 2 branches as per your diploma 

1. Computer science 

2. Information technology 

I think it's helpful for you.

Thanks 

Hi Mohan,

You can opt for Lateral Entry in B.Tech. You can get admission directly into second year B.E/B.Tech. You have to study for 3 years(from 2nd year,3rd year, 4th year).

I hope this helps you.

Good Luck!!
