SMEAT

Well, you haven't asked about a specific programme, but since you tagged engineering, So, I will consider you as an Engineering aspirant. There are two points here to be noted:
1) If you have more than 90% aggregate marks in 12th class, then LPU NEST exam will be exempted.
2) If you have less than 90% aggregate marks then you will have to appear in an exam of LPU NEST. Where as eligibility criteria is that candidate must have 60% aggregate marks in 12th class and English must be studied as a subject.
3) Thus, if any candidate will be having less than 60% aggregate marks, he will not be eligible to take Admission in B.Tech. For more and better Information you can call them on their Toll Free Number or you can visit the University Website. Online Admissions are already going on you can proceed further through their University Website www.lpu.in
All the best.
