ADHD- oxford application

This year, I am undergoing an ADHD diagnosis, which was only flagged to me after joining 6th form. I believe this has affected my GCSE grades significantly, as I was achieving 9 grades with a couple of 8's throughout my mid-term exams. However, I found it incredibly hard to maintain focus during external exam conditions, frequently losing focus and zoning out.

I managed to attain 3 grade 9's, 3 grade 8's, 4 grade 7's, and a grade 6, which I don't feel accurately represent my academic capability. Due to new access arrangements made for myself and hopefully starting medication soon, I am applying myself much better to my studies and am predicted A*A*A after my mock examinations.

I am wondering if such circumstances would be taken into consideration during my application, as I don't want my GCSE grades to put me at a disadvantage when applying. Thank you for taking the time to read this.
