If NIT Trichy is your only option, then you can go for it. But for Civil Engineering infrastructure can be a vital factor. 

The budget that usually is allocated for infrastructure incorporates buying lands from peasants to fund the research later on with a low-cost housing or environmental impact assessment. 

If you have chosen Civil Engineering, based on your electives, you could opt to specialize in Hydraulics engineering, Structural engineering, Environmental engineering, Building materials, Geotechnical Engineering, Transportation Engineering, Construction Management, Infrastructural engineering, and other relevant disciplines. 

It is best to get familiar with the topics briefly noted above. Based on your knowledge and expertise, choose one (or more, if required) of the many specializations and then do a brief research on the basic amenities, like faculty strength and similar aspects of NIT Trichy. 

However, in terms of academics, NIT Trichy is an excellent choice.

The answer would be Yes. One of my friends had completed B.Tech in Instrumentation and Control Engineering from NIT Trichy. The course is definitely tough but the level of difficulty perceived may differ from person to person. And here is some of the information about the course.

Sheer multi-disciplinary nature of subjects :

• In the very same semester, the candidate will have to study a varied range of subjects such as Fluid mechanics, Material sciences and Circuit theory. 
• All of these subjects require a good knowledge about modeling in different areas of Physics as it is one of the most essential skills of an Instrument designer.

Involvement in Laboratory activities :

• Practical knowledge is very important. 
• Most of the lab exercises are worked in a team. 
• Thus to complete any task starting from designing, experiment and analysis within a particular given time is a bit of a challenge. 
• It is important for all the team members to work efficiently for the task to be completed.

Programming and Analytical skills : 

• It is important to have a good hold on C/C++ programming to understand subjects such as Data structures/Algo, Embedded systems, Control systems design.

Product design and Development :

• The candidate needs to come with new project ideas and develop it from scratch and make it an Industrial prototype. 
• This will require a lot of outdoor work, market surveys, meeting suppliers and customer feedback. 
• Teamwork is very important for such activities.

Design specification :

• Right from the lab exercises, most of the projects and products the candidate needs to work on have a clear Design Specification. 
• It is important to adhere to those specifications as it demands sincere and laborious efforts from the candidate which might be tough. 
• The faculty or project guide may also make things tougher.

These were some of the aspects that make Instrumentation and Control Engineering tough. The course is pretty involved and demanding. Though all these mentioned aspects and skills are required to be a successful Instrumentation engineer.

It’s difficult to compare these branches or any other branches of engineering until and unless you specify the parameters of comparison. Scope, placements, future opportunities, etc., play an important role in differentiating the branches. Also, you should choose based on your interest and future goal while opting for a branch rather than on such parameters.

Now, if you do not have any interest in any particular branch and like most of the students out there, are doing it for the B.Tech tag, you can opt for any of the branches. Both the branches at NIT Trichy are at par. You will get decent placement opportunities from both the branch, provided you maintain decent CGPA. According to the recent placement highlights, the average CTC offered by NIT Trichy is 6 LPA. 

The hostel facilities provided in NIT Trichy are excellent. There are many hostels in this college but the best hostel for the students is the Diamond hostel. 

• Diamond hostel: The facilities available inside this hostel are amazing and the ventilation available inside the rooms is top class. The hostel is located in a very good spot with the mess, canteens, and lecture halls are nearby. There are also two well-maintained rooms which are specially made to play table tennis.

There are some other hostels too inside the NIT Trichy campus which are as follows.

• Agate: The location of this hostel is excellent but there are a lot of issues with the wifi speed and the ventilation available is not good.
• Jade: This hostel is also very good and is above average in everything except for the location of the lecture rooms and the canteen is very far away from the hostel and it is a big disadvantage.
• Coral: The location of this hostel is as good as agate but the condition of the rooms inside this hostel is very poor.

Before choosing a room, do check out the wifi speed personally as slow wifi speed can be very frustrating and it consumes a lot of time while accessing the internet. 

The classes at NIT Trichy start at 8:30 AM and lasts till 5:10 PM. There will be classes in two phases. The timing for morning classes is from 8:30 AM to 12:10 PM and for afternoon classes it is 1:30 PM to 5:10 PM. 

On some days, afternoon classes will be canceled and only the morning classes will be conducted. The number of cancelled classes depends from department to department. The CSE department has a lot of cancelled classes and you would be free by 3:30 PM. But this is not the case with EEE & ECE departments as here all the classes are conducted regularly. 

If you are residing in these hostels Garnet, Agate, Coral, Diamond then you can wake up before 5-10 mins of classes as it is located nearby to the lecture halls and you can easily reach on time. But if you are residing in Amber or Opal hostels, you will have to wake up at least 30 minutes earlier to attend the classes on time as the rooms are very far from the lecture halls. 

The timing for hostels depends upon the class. For 1st year boys, the entry timing is till 9:30 PM and for others, there are no such fixed timings and you can come at any time. But for girls, the timing is only till 9 PM and there is no exception in timings for anyone.

It's the case not just at NITT, but everywhere. It entirely depends on the visiting firm and whether they value your school percentages. 

The placement cell will have all of your information entered into their placement portal, and they will be aware of everything, so if you give the firm an erroneous résumé, whether intentionally or unintentionally, they will be notified. Because there are so many students, your college will try to set minimum eligibility standards for them by requesting or something similar. 

To make things clearer, I'll give you an example. 

1. Let's say Amazon Cloud is on the way, they've left the pointer criteria at 6, with no criteria in the 10+2 range.
2. Deloitte arrives on the second day and demands 60+ in 10+2+3.You won't be able to do anything because Deloitte does it all throughout India. Colleges don't matter as per their rules.

However, if a random startup comes along and offers a nice, attractive package and has policy rules similar to the ones listed above. But the placement cell can request them to ease the criteria if students have low scores. It now hinges on the company's reputation. It is applicable to every institute. 

NIT Trichy is a really good college when it comes to most NITs. But, you will only get admission through JEE Main. You will definitely have to score well if you plan to secure admission here. 

• About 90% of the entire paper is quite easy to solve at home but you will have to develop skills to be able to solve the paper quickly and efficiently. 
• See how well you can do with MCQs along with your boards’ preparation. 
• Develop your accuracy, for example, if you solve 30 questions, ensure that 18 of them are correct at least even if you end up attempting only 22 of them.
• As far as CSE or any good core branch is concerned, NITs are relatively easier to get into as compared to IITs. 

The cut-offs for NIT Trichy in CSE are as follows:

You will have to do your best and strive a little hard in order to secure your seat. Getting into core branches is quite tough especially for branches like ECE and mechanical. As long as you meet the above cut-offs, you should be good to go. Analyze your paper well, set a dedicated schedule and at the end, you will surely be able to crack the JEE.

One of my friends is studying at NIT Trichy and here is what they do on their weekends.

• In the morning at 5:30, you can grab a bicycle and ride to the temple near Opal. The temple is mesmerizing and peaceful, you may spot peacocks there.
• CCD is a two-minute walk from the temple, where you can have your morning coffee.
• There is a football ground near CCD, you can go for a walk or jog if you want.
• The campus of NIT Trichy has a brilliant and vibrant morning life. The students and faculty are often spotted playing lawn tennis or football.
• After having breakfast, you can head out to visit some places such as Tanjore Periya Kovil, Rock fort, heritage sites such as Srirangam, and Thiruvanaikovil. There is a church near Chatram which is splendid.
• For movies, you can visit LA cinemas or Vijay cinemas.
• There are all sorts of restaurants. One of the best is Hakkim, famous for its coffee. There are a few Dhabas too.
• You can go to Kodaikanal (4 hours away), Pondicherry (6 hours away), Bangalore (7 hours away) if you want to go outside Trichy.

It is up to you whether you want to go out of the campus or stay in. You can enjoy your weekend either way. 

NIT Trichy has a decent and well-equipped gym. The campus is widespread and accommodates around 10,000 people but there is only 1 gym for all.

You can book a morning or evening slot at the gym in order to avoid the humidity. However, it is manageable if you are quite passionate. There are certain gym groups and are approachable. If you do not will to be a loner at the gym then you might have to pull some strings to include yourself with them.

There are various students who install pull-up bars in their hostel rooms for themselves. Some have even rods and weights to lift and grounds around offer you enough space to run anytime.
