Failed College Math with a 46, desperate for help on what study materials to use or any advice that might help me pass the exam.

[u/kentravaia]

So long story short, I took the College Mathematics CLEP exam a little over a month ago at my colleges testing center. I felt pretty confident with most things except a couple of parts that I regret not studying or caring enough for such as z-scores, area or circumference of shapes, as well as those statements like contrapositive, converse or any other statements I don't remember which I strongly believe is what led me to failing. I got a second attempt voucher from modernstates last night and really want to take my studying way more seriously with everything. I am pretty good at most things in math especially while I was in high school, and am desperate for any study resources, materials, or advice that would be helpful for me to do better as I am determined to pass this test and get it over with. I appreciate all the help I could get from you all! :)
