Hi Aditya ! Yes you can earn a seat in lovely professional University through your ews ranking category. I am not sure about CSE or ECE but quite sure of other streams such as core streams and chemical and biotechnology. so hope for best because still it depends on cut off and vacancy ( for CSE and ECE ). So best of luck to you.

Dear friend, with this JEE Mains percentile, you definitely can not get admission in LPU. They take into consideration 80 percentile in JEE Mains. You can appear for LPU NEST exam, clearing which you will be able to get admission in B.Tech CSE and hopefully scholarship too.
