Diploma

For applying for any degree course you need to be 10+2, then only you can go ahead.

The B.Tech lateral admission are done for candidates who secure minimum 45% of marks in 3-4 years diploma from a recognized university sanctioned by U.P board of education and participate in UPSEE. Hence, you are not eligible here.

As per my experience and knowledge, you can get admission for B.Tech, because for B.Tech, the main requirement is that you have to pass class 12th with science stream.

You can contact them through call or mail by referring the following link: http://www.esacademy.org.in/contact.php

No, it is not. You need to study at home only for a distance course.

Hello,
You need to inquire with the college. What was the course duration of your Diploma course? Then, you can continue it from there.

Hi,
It depends on your background. If you already have a Masters in any other area then, it will be better to opt Diploma and enrich your skill set in business analytics.

That's not possible as admission is through counselling conducted by West Bengal State Council of Technical & Vocational Education and Skill Development based on the rank obtained in Joint Entrance Examination for Polytechnics (JEXPO).
For Management Quota candidates admission is based on the rank obtained in Shilpamandira Admission Test (SAT).
