Hello Devanshi Gupta,

According to the previous data,if you get 75 percentile in the JEE mains paper 2,then you have very less change to get seat in the colleges.So it is better to write the exam again in the month of April . And also make a plan for the exam and prepare according to it.And prepare more previous paper to know how the questions are going to given in the question paper.

For finding colleges that you are eligible ,you can find the by using the college predictor which link has been given below.,
