the informatica e-learning you can buy online on informatica site.
They don't have many of them. There's an overview, $160 & some on the metadata. And I think some more. They are a good start before you take classroom training. I don't particularly like the format of playing a flash video as it is a hassle to have to pause to digest a topic and they keep playing after the quiz to show you the answers before you are ready.
Most other CBT (e.g. the Cognos cbt) I've seen do individual pages where you click next when you've digested it and have multiple choice (with one or multiple options correct), 'where do you click' on screen-shots, drag multiple choices to their correct category, fill in the blanks, etc. to make sure you're paying attention.
Cognos even shuffles the questions on the end of course CBT. Made it harder and that much more fun to me. I kept retrying till I understood every question.
There are probably also 3rd party training places like there are for Cognos. And as people have suggested, read the manuals PDFs.
