Hey Aspirant.

See the marks u have scored in the JEE mains is too low for u to bag a seat in the good colleges like NITs IIITs or GFTIs for pursuing ur higher studies in the field of ur interest under the btech courses. U should be going for private Institution like LPU , MANIPAL , KIIT , etc for ur btech career. I m providing u a link for ur help.
