Fucked up the conversion factor, anything possible now?

I have 7.84 in my bachelors, we used to multiply it by 9.5 for percentage calculation and that is what I did while filling my CAT form. Yesterday I was talking to one of my friends and he imformed me that the conversion factor is now 10 rather than 9.5. Will this cause any problems? Can I do anything to rectify this situation?

Any help will be greatly appreciated!
