Ask HN: Lightweight Employee Training Software

I'm looking for a service (or a piece of software) that will allow me to train our clients' employees on how to use our product. Basically, I just want the employees to view a slide show with audio (or a screencast) and then take a quiz at the end. The results of the quiz should be saved and emailed to an administrator.

That's all I need. Does anybody know of anything like this that isn't too pricey?

Thanks!
