The IT courses at IIIT Allahabad are top-notch unlike CSE at BITS, Pilani’s. As CSE and IT are different courses and since you say that college doesn't matter to you it comes down to choosing between the subjects. IIEST Shibpur is doing great too in its infrastructure; placements and alumni base. The CST department has done great in the field of placements with 90% student placements in IIEST Shibpur. The highest was about 48 LPA from DirectI and the average package was around 8 LPA.

Notable Companies in IIEST Shibpur: Microsoft, Texas Instruments, Google (India, US), Directi, Accenture, Amazon India, Infosys TCS -CTO Digital and many more.

Notable Foreign Internships at IIEST Shibpur:

• (HCII), Human-Computer Interaction Institute, Carnegie Mellon University, United States of America
• Mc. Gill University, Canada
• DFKI (German Research Centre for Artificial Intelligence) , University of Saarland, Germany
• Nanyang Technological University(NTU), Singapore under NTU-India Connect Program
• Informatics Lab, Grenoble
• Amazon
• Google
• DAAD fellowship and many more.

In short CSE deals with the scientific study of computers and its research applications but IT deals with the industrial applications of the same science.

With the above information, I hope it will help you in clearing your point of view to opt between the colleges eventually.

I would suggest that you opt for Galgotia Engineering College. As per the experience of a few of my friends who are currently enrolled in one of the courses at the institution offers good campus life, infrastructure, facilities, fee structure, and an ideal environment for learning. 

In comparison with the other two colleges mentioned in the question, Galgotia College is better for almost every aspect mentioned above. The members of the faculty are well educated with over 10 years of experience in their respective fields. 

The table below shows the highlights of Galgotias University placements 2020.

Going by the above factors I will say Galgotia Engineering College, Noida is better than BIT Patna or Dayanand Sagar College of Engineering, Bangalore. 

KJ Somaiya has better placements and better infrastructure for Computer Engineering as compared to Shah and Anchor. Given below is a brief insight into the CS programs offered by these two institutes.

KJ Somaiya:

KJ Somaiya is among the well-reputed engineering colleges in Mumbai. The computer and IT department are one of the best departments in KJ Somaiya.

• Admission: The eligibility criteria for pursuing computer engineering is a minimum of 50% marks in 10+2 with Physics, Mathematics as compulsory subjects. The candidates must have valid scores in MHT-CET or JEE Main examinations. The course fee is 11.44 lakhs per year.

• Placements: KJ Somaiya has a dedicated placement department that conducts pre-placement talks and training. Every year, around 80% of the students get placements from the on-campus drive.

Yes, they are enough but only if you do not miss a single class, and are very serious about every assignment and internal mark.

Your professors and seniors would definitely suggest you the reference books and you should their advice. Everything is not about marks. You should have surplus knowledge about your subjects which brings completeness into the course. 

Due to time limitations, everything cannot be taught in the class. Also, engineering is beyond your semester syllabus.

ITM University is one of the emerging top private universities in the country. You might think that this is answer biased but personally I have no associations with any of these universities.

ITM University has grown tremendously in the last 6 years. The guests that the University invites in the convocation ceremony are no ordinary people but an alumnus at the university and you will be surprised to see the names. Here are a few names of the alumni:

• Mrs. Aruna Roy (ex IAS Officer, recipient of Magsaysay Award)
• Rajat Sharma
• Yuvraj Singh
• Shri Ashok Vajpeyi
• Padmashri Govind Nihalani
• Padma Vibhushan Dr. Raghunath Anant Mashelkar

Now, let us look at the comparison between the VIT University, Vellore CSE, and ITM University, Gwalior CSE.

• VIT is much older than ITM and thus, VIT outshines in case of reputation and facilities. The intake for CSE at VIT Vellore is 1200 but at ITM Gwalior, it is just 120.
• The infrastructure at VIT Vellore is much better than the infrastructure at ITM Gwalior. In fact, the infrastructure of VIT Vellore is one of the finest among all the colleges in the country.
• The fee at VIT Vellore is approximately 15 lakhs (hostel fee included) if you get selected through VITEEE (the entrance exam conducted by VIT). But if you go through the management quota or category system, you will have to pay a hefty amount of Rs. 30 lakhs, approximately. The fee at ITM Gwalior is Rs. 9 lakhs for 4 years (hostel fee included).
• Faculties are good at both institutions. There are faculties for M.tech and Ph.D. in both institutions.

Do not join VIT Vellore through management quota paying such a large amount, join only if you make it via entrance exam because it will not be beneficial.

ITM Gwalior provides you with good opportunities at a much lesser fee.

RGPV is a government college and because of this all of the courses which it offers are quite good to get a well-reputed job. IT or CSE will be the best option if you want good placements. According to the recent placement highlights the average CTC offered at UIT RGPV is 3 LPA.

Now, whether you will be able to prepare for UPSC, along with your engineering degree or not, that depends on you. 

• You can go for UPSC preparation whilst you are enrolled in IT. All of the possibilities depend on how motivated you are. 
• Moreover, if you try to finish learning your engineering courses on time, you will have ample duration to sit and study for UPSC.
• Furthermore, try to be with the group of students who are also preparing for UPSC so that you can be with them and prepare well with them. Studying with your peers will help you to achieve your goals easily. 
• Also, the syllabus for IT is quite easy so, you will have time to prepare for UPSEE. 

Thus, you can prepare for UPSC if you really want to, and choosing IT will make it easy for you to lower the burden of academics.
