What should I focus on for math prep for 18C?

[Soak60]

Greetings.

I am a contracted 18-XRAY, looking for general (or specific, if it doesn't violate OPSEC) math skills I ought to be focusing on to prepare for 18C. I AM focused on the 25m target in regards to conditioning/PT, but I've already done most of the exercises on the FS site and am looking to keep improving. I was in college for Mechanical Engineering for awhile, I've taken up to Calc3/ Differential Equations (though I would rate myself as only being comfortable and proficient in up to Calc2 level math). I've also taken Statics and Dynamics, SoM courses.

Do I need to simply read and review what I have already learned? Or should I take the opportunity in the fall (Sept-Nov) and take more math at a local community college?

Thank you for looking. I attempted to search this under "math skills" "engineering math" and "18C math" and was unable to find the answer. If I simply failed at searching and you have a link, no need for a lengthy post here, just slap me and point the way.
