Serious question ; CBSE Board , Accepted to UMN-TC for computer science, will I get rescinded?

Yes I did email them , they said :thank you for your email and the information about your marks. Please don’t worry too much about this! We understand that the situation is challenging for our students this year, and are correspondingly using our judgement to grant leeway on grades. I don’t feel that one lower grades (which isn’t that low) will affect your admission.

Now I am not sure if this really means its fine or what? I got a 80% in grade 11 and 90% in grade 12 midterms which were internals . but getting a 75% in grade 12 finals is a bit shocking for me. I hope they wont.
