All of the mentioned branches are core branches and are somehow interlinked by areas like automobiles, structures, and circuits. If you are eligible for all of these then it's better to sort your preferences now.

You should take time and decide which one among them holds your interest the most. This is quite important because your passion and interest will impact these 4 years and your career too. However, in case you share an equal interest for all the three branches, then mechanical is the best choice. Here’s why:

• Mechanical engineering is one of the best branches not only in NIT Raipur but in all the NITs of India too.
• The faculty of the mechanical department is quite good.
• The branch is also best in terms of placement and opportunities both in and out of campus.

The following table shows the placements statistics for Mechanical Engineering at NIT Raipur:

It's high time to choose the one branch which seems the most fascinating to you and can devote all your hard work into. At last, the right pool of interest is the key to the foundation of your career.

CS certainly holds more importance compared to IT in all the reputed engineering institutes irrespective of everything else.

IT at NIT Raipur is a good enough option to choose especially because of its HOD. He is very sincere and too much dedicated to the students and their well-being. Unlike many other departments and colleges of our country, he takes a special interest and personally looks into every student’s growth and academic performance. Starting from the appointment of the teachers for the various subjects to the handling of the detention lists, he does it all.

Moreover, the faculty here at NIT Raipur is overall a young group of teachers, which basically means they are way more enthusiastic and energetic. A couple of teachers from other departments also take a few subjects here at times.

Even the placements are quite well known here and although placements eventually depend on your throughout performance and scores. The following table shows the placement statistics of both institutions:

The environment offered to all the first years is much protected and they strictly follow a zero ragging policy. Seniors here are too welcome and supportive which ensures that all the students feel absolutely safe and secure.

NSIT Delhi is a leading institute in India and ranks 76 among the engineering colleges as per NIRF 2020 ranking. This institute is an excellent place for quality students and offers nearly 100% placements every year.

IIITM Gwalior is a fully IT-oriented institute and ranks 100 among India’s top engineering colleges as per NIRF 2020 ranking. This institute provides 90% placement to its students in top-notch MNCs. 

Admission Process 

NSIT Delhi:

• The essential eligibility criteria are a minimum of 75% marks in 10+2 with PCM as compulsory subjects.
• The final selection of the candidates depends on the JEE Main scores.

IIITM Gwalior:

• The primary eligibility criteria is a minimum of 75% marks in 10+2 with PCM as compulsory subjects.
• The final selection of the candidates depends on the JEE Main scores.

The following table gives a brief overview of both institutions:

Placements:

The placement scenario at IIITM Gwalior is one of the best than other IIIT's. 

Mostly all the top companies, including technical and non-technical visits, every year for the placement process at NSIT Delhi.

The top recruiters are Google, Cisco, Amazon, Microsoft, Dell, IBM, Verizon, Accenture, Wipro, Flipkart, Adobe, etc. 

Both these colleges provide quality education with successful placements. The students pursuing a course in any of these colleges will be an excellent choice.

Firstly, you should know that there is no difference in the facilities and reputation of the colleges, Although BITS ranks better as an engineering school. BITS Pilani ranks #30 on NIRF's Engineering rank list and IIIT Allahabad ranks #103 on the same. But you should focus on your monetary capacity in consonance with your future plans before applying. 

My cousin studied at IIIT A and the following points are based on his experience:

• IIIT A is an excellent place to study coding. The classes are good although the syllabus has to be maneuvered because it's tough. You can manage it through attention in the classroom.
• Attendance is an important part of the academic process here because IIIT A has a 75% mandatory attendance rule.
• Without a doubt, BITS has a higher fee range as compared to IIIT A, about 7 LPA for a 4-year program.

Here's a table comparing both institutes:

Lastly, if you love the mechanical stream and are truly motivated to study Maths and Physics then you must go for it. Mechanical is a vast field as well because you'd learn everything related to mechanical processes and even production scheduling. So clearly check your interests and goals before deciding.

UIT RGPV is good for Mechanical Engineering. However, things vary with each one of us.

If you want to prepare for higher studies like MS or competitive exams like the GATE or CAT, it is good because you will get a sufficient amount of time. If not, you will end up working in companies like TCS being graduated in Mechanical Engineering from UIT RGPV.

Check the following table for some brief statistics about UIT RGPV:

If you have better options you can opt accordingly. UIT is good for B. Tech in Mechanical Engineering you can pursue.

Civil Engineering and CSE are the trendiest branches as reckoned by the leading companies. If you will opt for a better college over a preferred branch for pursuing engineering then it is suggested to switch your opinion. 

Seeing this, you must choose Civil Engineering at Jadavpur University over KGEC. Following are the reasons for choosing the same:

• The faculty at Jadavpur University is comparatively better than Kalyani Government College. They are well-experienced and most of the faculty members hold a doctorate degree. 
• The student crowd at JU is helping and competitive. One of the main highlights is the students’ club in the university. You will receive good exposure.
• Although the placement scenario for the civil industry is deteriorating in the entire nation, it is still better to take it up at Jadavpur University than Kalyani for CSE. 
• The mass recruiters are mainly limited to companies such as TCS, Infosys, etc. at Kalyani. Whereas in JU, you would be able to opt for financing and consultancy firms as well. They certainly provide contenting packages.

It is suggested that you choose your preferred stream if you ultimately have planned on pursuing higher studies like GATE, GRE, etc. If you are planning on doing MBA or some job then JU would be the best fit. 

You should keep in mind that the name tag of your undergraduate institute always stays with you hence choose wisely.
