Crissia,
Great! I use pretesting intermittently, usually for a new cohort of students (when I'm unsure at what level students are performing at). Like you, I find the biggest value is planning on where more (or less) emphasis may be needed in a course. A couple of times, I've had students redo the same pretest at the end of a course to show how far they have come. But as a practice I don't simply because it's somewhat redundant.
