Your subject preference should be completely based on what you are interested in. But CSE, EEE, and ECE are some of the popular courses at Thiagarajar College of Engineering.

ECE or EEE:

• There is a Technology Business Incubator set-up on the campus, the TIFAC-CORE is only available at fewer places in India. It is a center of excellence for wireless technologies and is an anechoic chamber for several antenna testings and characterizations. 
• This is the reason why opting for either ECE or EEE specializations can be the best. Not only you will have great exposure theoretically, but practically as well.

CSE or IT:

• Opting for either CSE or IT can also be a good choice as well since they have the highest placement records over time, and several top-tier companies visit the campus placements, such as Amazon, Microsoft, Uber, Google, and various more. 
• Alongside, Thiagarajar College of Engineering (TCE) has achieved the Best Student Branch Award for the CSE department by the Computer Society of India. Thus, it can be a brilliant choice to go for. 
• Also, TCE has collaborated with multinational companies like Yahoo and Honeywell, and they provide great opportunities to the students.

These are some of the things that you should consider while choosing the right branch for you.
