One of my friends studied in the PSG Mechanical branch. In his opinion, both the colleges are well known and quite famous for Mechanical Engineering. Let me state some facts about them which might help you decide.

• NIT Trichy holds a certain advantage over PSG. 
• It is considered one of the top 5 NITs. It has earned recognition not only in India but also globally.
• In NIT Trichy you will get much more opportunities and the proper exposure. 
• PSG is not bad but while comparing it with NIT Trichy, it gets more leverage. 
• In PSJ the faculty members are really good in their respective fields. 
• In PSG students mostly like to learn their subjects by themselves and are independent of the teachers. 
• NIT Trichy has all the things required for such a core branch, like Good faculty members, excellent academics, internships, connection with industries, placement statistics, etc. 
• All this makes NIT Trichy a better option for Mechanical Engineering.

NIT Trichy develops your physical as well as holistic personality. It makes you confident with all the extracurricular activities it has to offer. Nit Trichy would be better overall and will definitely help you grow as an individual.

I know a little bit about ISI Kolkata since I have a few friends from the institute. Here is what you should know about the internships between semesters. 

The course curriculum specifies that in the summer after completing your first year of M.Tech, you have to do an internship either in the industry or academia. You will have 3 options. 

Industry:

• Many companies that visit the Campus for placements of 2nd-year students also select interns for the same.
• Some of such companies are Samsung Research Labs, Google, General Electric, Reliance, Flipkart, De Shaw, JP Morgan Chase, etc.
• The average stipend offered last year was 65,000 rupees/month.
• Some companies offer more than 1 lakh/month. One of my friends interned at Samsung Research Labs.

Academia:

• As per ISI guidelines, you need to pursue an internship at a different academic Institute or industry.
• A friend of mine went to NUS Singapore, while two others went to a university in Germany. You can also apply to other institutes in Japan, USA, and Europe. People also go to IITs, CMI, and other Tier-1 Institutes of India.

Within ISI:

If for some reason you could not get an internship in the above-mentioned ways, you can approach any of the 250+ faculty members across all 5 ISI‘s and can ask to work with them in their labs.

You will have internships at the end of the first year. In the second year, you will have placements, dissertation, academics. So, the only time left to do an additional internship is the winter break after the first sem. Unless you are extremely enthusiastic, I will suggest that you take a break during this period. Because after the break you will be swamped with coursework for 1.5 years.

Yes, you have a good chance of becoming eligible at NIT Trichy. Since your score is what you have mentioned above, it translates to your rank being somewhere 1,000 or 1,200. As per your rank, you have a sharper edge at securing admission in the CSE department of NIT Trichy. 

However, here is a detailed cut-off list of NIT Trichy for equivalent disciplines, alongside CSE as well:

Apart from this, you can also vividly research more about other rounds, and categories, at your convenience. Hope this helps answer your question, wish you all the best!

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.
