My brother was in the CSE branch of NIT Trichy and based on his experience, here are a few pointers:

• The professors are extremely learned and experienced and impart quality education
• The relative grading system establishes peer pressure, and as a result, there is tough competition among the students 
• IIT Roorkee is well known for its rich coding culture that is promoted by student-driven and institute funded clubs. These clubs give you additional knowledge on web designing, App development, and game development that might be useful later in
• The CSE department is one of the most coveted branches, and being a part of one will inculcate a sense of privilege.
• The hostel and campus life is decent with all necessary amenities.
• A total of 5 fests are held throughout the year and are totally funded and organized by the institute. The institute is located in an area that helps you explore nearby tourist spots like Pondicherry and Ooty.

You won’t ever regret choosing NIT CSE.
