Yes, there is an option of lateral entry in the second year after Diploma.

Hello Siva,
The situation is pretty dynamic from the second round onwards. Suddenly some unexpected seats pop up. So keep your hopes alive. It's quite possible that you may get your desired branch.
Best wishes.

There is a wide difference between the fields you are talking about and you can study further in any branch you take up, I would suggest that choose a field of your interest. And yes if you wish to study abroad then definitely DJSCOE has an upper hand as it provides more exposure.
All the best.

Hello Raushan,
Yes, you are eligible to get lateral admission in engineering after the completion of your Diploma. How you got admission is of no relevance. What matters is how much marks you have obtained in Diploma.
Best wishes.

Since the first batch of petroleum engineering hasn't graduated I can tell you about their placement but the MBAs got a decent placement in the past years. So you have chances to get good placement in B.Tech as well.
