Hi Himanshu, hope you are doing well, I am sorry to say that with your rank of 129100 rank in jee mains you can not get into good colleges like iits and nits. But I suggest you go for lpu, it is good both in placements as well as academics. It is also cost effective. To know more about the admissions through jee mains go through the rank predictor in careers, the link is provided below, kindly go through it
