Hello kushboo

First of all I would like to tell you that you must check this year format of medical certificate in Jee main brochure. Also if you have used previous year format, date would have been of previous year, so check date and match format.

One thing I would like to tell you that medical certificate are not given much importance just it should be of their required format. 

Good luck for your counselling!

Feel free to ask if you have any further queries.
