Which IIT is good for electrical engineering (if I am thinking of a branch change to CS afterward), IIT Mandi or IIT Jodhpur?

In case you are considering a branch change, the better option between IIT Mandi and IIT Jodhpur is the latter. Here are 2 solid reasons that support my stance.

• The batch size of IIT Jodhpur is small with around 60 students only. As per the branch change policy, 5% of the batch can change their branch and the total strength can be increased to 5% only. This policy works in favor of CSE students who are more in number. This is because the higher the number of students per branch, the higher will be the chances of the branch transfer.
• Secondly, if you are unable to get a branch change, IIT Jodhpur has an excellent alternative plan. It has a unique program called IIP under which students get 3 years of internship. On the basis of your performance, you might get placed as you hold a strong resume. This program is unique and no other institute offers it. This ensures a safe alternative in case of failure to change the branch. 

In the end, it’s better to visit the websites of both IITs and go through their programs, as well as talk to current students or alumni to get a better sense of which one might be a better fit for you.
