Both the programs, Chemical Engineering at IIT Madras and Computer Engineering at IIT Indore offers excellent courses and opportunities. However, the choice of the program is more of a personal decision as it depends on career goals, personal interests, and other criteria. It's not a hidden fact that Computer Engineering has a wider scope in almost all sectors in comparison to Chemical engineering. So obviously it is a safe option, but what if you take a specific branch just for placements and then regret it later? 

If you take Chemical you can also change your branch to Computer later but it won't be possible Vive Versa. You must decide after considering all factors and most importantly your interests. Find out what makes you happy the most out of coding, data analysis, or research in a chemical lab, finding solutions for medicinal products, health, synthetic materials, and so on. 

There are examples of IITians dropping out to chase their dreams after realizing they were chasing the wrong branch. Only you can identify your innermost driving factor that will sustain your happiness later on in life.
