Dear Priyadarshini Singh,
Prefer United School of Business if you are able to secure admission there. Because comparatively, IEM is getting lesser salary package than United School of Business. Even international placements are coming to Universal School of Business.
All the best.

Try to pursue it based on your interest but I would suggest you to purse chemical engineering but see to it if you are good in chemistry, go for it.
All the best.

Yes, you can change it through lateral entry.

I wish I could help you with this. But this is purely individual choice and I cannot choose a course for you. However, when you consider the choices, look into factors such as your field of interest, budget and what you hope to gain from the course.

There is no area wise preference in any of IIM becaause selection in IiM is purely based on merit.
