Yes! You can get admission at LPU without appearing for LPUNEST for many programs, the university also accepts your qualifying marks (like Class 12 or graduation scores) or valid scores from national exams like JEE, CAT, MAT, etc., depending on the course. However, LPUNEST is super helpful for scholarships and better chances in competitive programs, so it’s usually recommended even if it’s not strictly mandatory for every course.

Dear Student,

For the International Institute of Hospital Management & Allied Health Sciences, Kalyani (IIHMAHS), if you want to enrol in their Bachelor's in Hospital Administration (BHA), you should not take the WBJEE exam. Instead, the institute requires a rank from JENPAS UG 2026.

Thank You
