I see that you are pretty confused between chosing the right choice for you. You have provided pie in MNNIT Allahabad and mechanical in nit kurukshetra. It is a tough choice , but you need to choose. 

See if you are interested in doing business or all or doing MBA . Then pie would be the best option and MNNIT Allahabad is a good college also. 

But if you are more inclined towards core sectors joining PSU and all. Then go for mech.

But you have to make final decisions. Choose wisely.

Thank you.
