Hi, youe best of four percentage comes out be 92.75% if you add the marks of all the 4 subjects. But if you wish to opt for Pol science as one of our subjects you will have to include it in your best of four marks or 2.5% will be deducted from your best of four percentage.
You can the Gargi college brochure on how to calculate best of four from the link below:
