Yes. This is the problem for me. The only description of arrays is what I've pasted above from the lesson. I'd never heard of them before and all I currently know about them is that I will use them when I "need to store an ordered list of values."

I'm not sure how much I need to know or understand about them at this point, either--I speak some human languages that are not my native tongue and I was very lost when I first began learning them and relied heavily on memorization. What I need is just to be able to follow along well enough to produce an answer and for there to be enough repetition and regurgitation that things start to gel if I keep it up.

This wasn't clear enough for me to be able to continue with the lesson; I was literally stuck since there weren't any more hints or resources (though I have since downloaded an e-book ;). Perhaps it would be good for there to be a cheat revealing the answer and additional problems that appear whether or not you fail the first time.

This format is excellent and the site looks great. More coddling, please!
