Are there ACP-100 prep resources available OTHER than Atlassian University?

[Rob Horan]

Having taken the beta exam and missing passing BY A HAIR I can tell you that studying the admin guide is useful but it is NOT the end, nor is being an admin for a long time - why?  Because realistically, unless you need to utilize every function JIRA offers, you're most likely going to be focused on only what you need to use in your time as admin.  

So now I'm looking for prep material, but the only thing I can find is a $150 pre-recorded course from Atlassian University.  BUT WAIT, it gets better!  For your $150 you only get access for 120 days!

So... are there any alternatives before I break down and shell out the cash, out of pocket?

You might need to create your own new CustomFieldType, which can handle both the logic and the UI for what you need.
