NIT Trichy has a brand name higher than SSN. However, if you are planning to do higher education such as MS abroad, then regardless of the brand, you should choose SSN as it will help you to grow academically. 

Instrumentation and Control engineering of NIT Trichy is a tremendously demanding branch. I have a few friends from NIT Trichy and according to them, the department is great. Except for a few of the faculties the faculty members are cooperative. 

In fact, in this branch, you will be exposed to a very healthy learning procedure. Most essentially, the department of Instrumentation and Control engineering has a broad and diversified curriculum. You can ask some of the alumni members to walk you through the subjects, electives, curriculum, and other relevant areas of concern. 

The first and most important thing to know is “Nothing is difficult”. If you are finding difficulty in engineering then you lack passion and motivation. If you are passionate about Instrumentation then you would not find anything tough.

The atmosphere at NIT Trichy is quite competitive and you should be well prepared to score good marks in your respective branches. You might find some challenging professors. The course curriculum for Instrumentation is a blend of Electronics and Coding. It is also one of the fast-growing industries.

Here is the placement highlight of the year 2020.

NIT Trichy is one of the finest engineering institutions in India and you would surely get the best learning experience and knowledge. In terms of getting admissions at NIT Trichy, then one might say that it is a little bit difficult but not impossible, just score well in the JEE Main.

I have friends pursuing courses you mentioned above at either institute. Based on the discussion I have with them, here is what should be best for you,

1. The institutes can be considered quite equivalent to one another, but BITS Goa has an upper hand. 
2. M.Sc at BITS Goa can be specialized following the first year, during which you will be allocated a B.E course depending upon your CGPA. 
3. With a 6 CGPA, you can get Mechanical Engineering, which is quite an easy job. In contrast, it is better than ICE.
4. However, if your scores are high enough then you might get a seat in CSE. 
5. By the end of 5 years, you will be receiving a B.E and an M.Sc degree, which is nonetheless a smarter choice. 

However, the fees at BITS Goa are quite a lot. 

There is nothing called instrumentation engineering. The students usually study the syllabus of the electronic branch that includes learning low-level languages along with the complete command of them. 

• There is a very high demand for highly skilled engineers who know the top programming languages like TopCoder, GitHub, and many more. 
• Learning these languages totally depends upon the person that they can do without going to college.
• Becoming an electronics engineer totally depends upon the person, and their effort, not the college. 
• Some of the students follow the GATE syllabus to enter into the government sectors. 
• Some get recruitment in top private companies by learning these programming languages. The college can help you out only by giving a proper study environment that can promote your overall development. 

If you wish to join the private sector, then only the placement facility provided by the college is useful to you.

Last but not least we can say that the college for the instrumentation branch is the version of the electronics branch of engineering. It totally depends on you how much effort you are putting into the same and not depend on the college.
