When are the official NEET answer keys released by the CBSE?

Dear aspirant,
Thank you for asking your doubt.
The neet exam will be conducted on first sunday of may. The results for the same will be declared in a span of 4 -5 weeks. Before declaration of results, the cbse uploads neet question paper and answer key along with your omr sheet. These three things are uploaded on separate days. But once they are uploaded you can precisely calculate the marks. Unless and until there is change in answer key, the calculated marks won't be aberrant from your actual marks that you will score in neet.
I hope my answer  was helpful.
All the best with your preparation.
