My brother prepared for the Written Examination only in a week and scored close to 110 out of 150. 

Since my brother had a background in Semi-automated Trading, the interviewers were convinced about his love of Finance and Maths. He got waitlisted in 5 of the General Category lists and declined admission after the results.

If you are good at JEE Maths and have contributed to the field, it is important to show your passion to the interviewers.
