It is really exciting that people are interested in thermodynamics and fluid mechanics. There are many other topics in chemical engineering that you will start loving when you start reading them. 

If you are genuinely interested in the subject then it will completely be your effort in approaching the professors to learn and to study more. 

There are not many professors in the department. Most of them are Ad-hoc teachers who will be teaching the subject. If you wish to go for higher studies, it will be your effort in asking the faculty to help you out. 

If you talk about the placement scenario, there are only a few core companies that visit the campus along with a lot of non-core companies. Overall, college life is good in the department of chemical engineering.

Chemical Engineering at Haldia Institute of Technology used to be one of the best courses at the institute. But with years the condition of this branch has gotten worse. The old faculty members have retired. The current faculty base is not that great. 

I have a few friends from the institute and according to them, if you are keen on exploring the field of chemistry then Haldia would not be one of your best choice institutes. But the placements here are decent. In the 2020 placements, the highest and average CTC offered was 3.5 LPA and 24 LPA. 

My friend is an alumnus of IET Lucknow and according to him, with a rank of 5915, it will be hard to get Chemical Engineering. In his year, only a few general category students received Chemical in the fifth round with a general rank greater than 6k.

However, because the scenario changes every year, there is no certainty that you will get it. Also, given HBTI's split from UPSEE, getting into IET with this rank appears to be extremely difficult. It's all a matter of luck. 

According to the cutoff trends in recent years, the required cutoff for the Chemical branch is 2856 for General Category.

If you are interested in coding and aim to work in good corporate firms, then it is suggested that you go for CSE at NIT Calicut. But if you want an IIT tag, you can opt for IIT BHU. But this won't matter much afterward.

So, if you are focused on doing research then Chemical Engineering at IIT BHU will be a good option. You can also learn coding on the sidelines, which might be beneficial if you sit for placements.

The choice of studying in a college pursuing a particular subject is entirely up to you. Check where your strengths and weaknesses lie and then choose accordingly. Both institutes are good in their own way. But it is your hard work and dedication that will prove if CSE or Chemical will be good for you. 

The fee for NIT is very less as compared to BITS Hyderabad/Goa. BITS Increases its course fees by 15% every year. 

However, in BITS Hyderabad/Goa, you can apply for a loan and easily avail it. Around 20 to 30 percent of the students apply for it. 

If your net family income is less than 8 lakhs per annum then you are eligible for the merit-based scholarship based on the CGPA at BITS Goa. You can apply for the merit scholarship even if your family’s net income is more than 8 lakhs per annum based on the CGPA. Financial support is given to deserving candidates on the BITS campus.

The answer to this question depends on what you aim for after 4 or 5 years of your college degree. If you just want a placement and not particularly interested in a branch then you could go for any of those two branches as placement statistics are good for both in IIT BHU. There are enough opportunities in the non-core sector which generally comprise IT, developer, analytics, product management, business analyst, etc. These sectors don't look for a specific branch and rather require good communication and analytical skills. 

Coming to the core sectors, both civil and chemical provide diverse opportunities in these areas. If you are someone who finds chemical processing and chemistry interesting, then go for chemical engineering. If you are the one who gets amazed by the interesting and defying structures, civil engineering should be your choice. According to 2019 placement statistics, 77 students from Civil Engineering and 104 students from Chemical Engineering got placed from IIT BHU.

Opting for civil engineering would open doors to exams such as IES, UPSC, GATE, and other state engineering exams. There are ample opportunities for civil engineering majors. And if you choose chemical engineering, you can go for higher studies or work for PSUs. So, both these branches at IIT BHU would provide enough opportunities to grow and explore and the end decision should be based on your interest.
