I took the ASVAB in a Marine Recruiter since the Air Force Recruiter wasn't around.

Hello everyone,

I just took my ASVAB exam and saw my score. I wanted to change my branch since I already set my eyes on the Air Force, but the recruiter for the Air Force wasn't around at that time, so the Marine Recruiter interviewed me. Do I need to retake my ASVAB when I decide to pursue the Air Force or not? I'm also wondering since I scored 65 in my ASVAB, can I set my eyes on Space Force? Should I go directly first to them before the Air Force?

I have my appointment again with the Marine Recruiter this Monday and I'm already final with my decision to join the Air Force. What is the most polite way to decline the offer though since they were also accommodating?
