I have made a mistake in CAT 2021 application. Details in are below

I have got 9.3 in AP SSC board with 56 points out of 60. The conversion rate is 10. Since, I did not have marks in the certificate, I have used 56 marks out of 60 marks in CAT 2021. The application gave me 93.33 percentage. So, application has 0.33 percentage more than the actual 93 percentage. I have completed the CAT 2021 exam. Is there a way I can rectify this mistake? When and where should I raise this?
