Please list these AP cles in order from easiest to hardest....?

For a sopre, I'd recommend AP Environmental, AP Statistics (provided you will have completed Algebra II), or AP Psychology. I've never taken Psychology or Environmental, but they're considered to be relatively easy. I did take AP Stats as a sopre (along with AP Bio and Human Geography). On the first day of AP Stats, when we got our textbooks, I was intimidated by all the huge formulas, but honestly, it's all calculator work and ysis of results. I think the only reason why Algebra II was a prerequisite was because of the huge formulas.
