Hey Saurav, you can apply either on the basis of your jee mains percentile or 10+2 percentage. It depends on through which you can easily get admission. 

I would prefer you should apply through jee mains paper as at 53.4 percentile you can easily get admission in Chandigarh Group of Colleges Landran Campus, Chandigarh.

Hope this helps.
