What order should I take these CLEPs?

[Doodlebabe]

So I fell off the bandwagon because life got crazy and am way behind on where I wanted to be with getting my BALS (TESU) done. I'm not 100% sure if I'll take all these CLEPs but I started the courses on Modern States for all of them - or registered anyway - and am hoping to at least do a couple to cut down on classes I'm going to take through Shmoop. Life is still crazy and going to get a little more chaotic here soon so my degree is still going to take longer to get than I want, but if I can manage my time effectively I'd really like some advice from those who have taken these tests. From easiest for those with prior knowledge to hardest and needing a bunch of additional studying, could I hear some feedback and/or a ranking on these CLEPs? First one being the easiest, last one being the hardest if you rank them.
