How to get A ranking with Special Week?

Hi Reddit! I'm relatively new to the game (i've been playing for a week and have 124 hours), and I've been slowly working my way up to A rank on my Uma.

Currently I've gotten A rank on five trainees, but Special Week is evading me. I've gotten her up to B+ multiple times and have her potential level and stars both at four (which is higher than I have on any other uma), but A rank Special Week still remains outside my grasp.

Special Week is my favorite Uma by far, so I want to get her as highly ranked as I can. Does anyone have any tips on what I can do? What support cards and legacies would you guys advise I use?

In case it helps, here are my current Support Cards and Veteran Uma:
