Hi, Admission under JEE Joint Admission Committee (JAC) has been constituted for conducting admissions to B.E. courses based on JEE (Mains) in UIET. All India Rank prepared by CBSE on the basis of score in JEE (Mains) and normalised score in Class 12 or equivalent qualifying exam (60% & 40% weightage respectively) shall be used for admission to B.E./B.Tech. for JAC. The cut off marks/criteria for eligibility for various categories shall be decided by CBSE on the declaration of the result of JEE (Mains).

You can check the criteria officially here: http://uiet.puchd.ac.in/images/PDFfiles/information%20brochure.pdf

If there is any change, officially it has not been updated yet.

Good Luck.
