Elisha,
If possible, I recommend taking the regular OCA instead of this exam. See
here for why.
If you need to take the Foundations exam,
see this writeup for how to study for it. The gist is to use any OCA book along with some supplemental posts I wrote.
There are no practice exams dedicated to this exam. So you'd have to use OCA 8 exams plus practice questions like those in the blog posts.
