How to ce73 phase7 s rank?? unlock savior?

Hello,



Anyone have any ideas of how get S rank ce73 phase 7? I'm trying to unlock the savior gundam and highest grade I keep getting is an A. I brought down Gaia, abyss,chaos, cagali, freedom in the first part. On the 2nd part I chose to stick with zaft and took down freedom and cagali then the 2 orb ships. I cannot seem to manage to get S. Any tips.




Please help

Thanks
