Greetings Aspirant,

I hope you are good with your health.

I didn't get your question correctly. There are no such branches in engineering as Lower branches or top branches.When you ask me about whether it's IIT or NIT. Then I would say go for IIT. As it's really simple one to deal with.But, If you could have given me the name of the branches. I would compare and answered your question with ease.So, I want to Re-write your query or comment it below.

Hope this is on the point.
