hello,

actually AIEEE stands for all India engineering entrance examination. it was replaced by JEE mains , which stands for joint entrance exam.

it is entrance exam for engineering colleges across India. so, it is a national level competitve exam , through this students get admission to various engineering undergraduate programs , also architecture colleges that accept this exam score , it also includes admission to IITs , NITs and other institutes . now ,this AIEEE exam is called JEE mains , that provides admission to IITs , NITs and other engineering institutes and colleges throughout India.

hope it helps,

all the best.
