Everything has a price in this world today. It can be monetary or through the dint of your hard work.
Regarding LPU you have asked about free admission.Yes you can get a free admission in a college if you have won a national award like it was in the news that LPUs weight lifter Usha Rani entered the Asian Games. She was studying not only with full fee waver but also her hostel and food was sponsored by the university.
Yes, LPU does give scholarships based on various scales like last qualification, category, disability, sports, cultural and entrance tests of LPUNest, CAT etc.
It has also started the scholarship to aid education in the grim times of covid.
Best would be to browse the website the LPU to know details.
Hope I answered you
Good Luck!!
