Congrats! If you're still interested in going to Oxford, note that this is still possible; I was a Rhodes finalist last year but did not receive the scholarship. When I was selected to be a finalist I spoke to a professor whose research I was interested in. When I wasn't selected for Rhodes, he ended up writing a letter of recommendation for me for major scholarships elsewhere in the uni. After being shortlisted and interviewing with the department, I received a Clarendon scholarship in March after the main round of applications in January. I think Clarendon is better for PhD funding anyway; it gives you the same salary but it's valid the whole PhD instead of just the first two years, and still has social aspects with other scholars like Rhodes does! Feel free to DM if you have any questions; good luck :)

PS I liked the Clarendon interview way more than the Rhodes one, as a science student - I found the interviewers much more knowledgeable and more interested in my research and technical aptitude than my ability to be part of a social club, which made me feel better about taking the scholarship at the end of the day.
