Should I take IIIT Delhi or IIT Mandi? I wish to take electrical in Mandi and CS in IIIT Delhi?

Both IIT Mandi and IIIT Delhi are excellent institutions with well-established programs in Electrical Engineering and Computer Science respectively. The decision of which one to attend should depend on your personal preferences and academic goals rather than the quality of the branch. IIT Mandi is known for its strong emphasis on research, while IIIT Delhi is known for its focus on applied technology.

Both colleges give an edge to each other in terms of placements and quality of education offered. If you aren’t certain of your preference yet, it's best to go for IIT Mandi. There are 2 main reasons why I prefer IIT Mandi to IIIT Delhi.

• Firstly, one can never underestimate the value of the IIT tag. It’s like attaching yourself to a branch for the rest of your life. 
• Secondly, IIT Mandi is well known for its lenient branch change. This helps you explore multiple branches in the first year and then finalize the most preferred branch in the second year. It’s a win-win situation in either case.

However, solely relying on branch change is not wise and you should analyze other angles also.
