I am stretching my memory but I think that the Blue & Gold Officer will have whatever information has been submitted with the application thus far via the online portal. I recall that he had a file with him with information about my son, and we did not have to provide anything on the spot during the interview. When my son sat for the interview last fall, all of this was still a work in progress. He had taken the SAT but was going to take it again to raise his scores. He had passed his CFA by that time, but I don't think that the CFA needs to be done by the interview.
You could always try and contact the officer. Ours was friendly and helpful.
Our son prepared a "resume" for this interview, listing his GPA, class rank, SAT/ACT scores to date, sports, clubs, leadership roles, and part-time job info. This was not required. He just did it based on a recommendation we had received from someone else.
