Troubleshooting resources for R&S

All,

I need to know people's honest opinion. I need a self-study resource
(can be workbook or whatever) to train speed for the R&S
troubleshooting. I had a lot of difficulty sorting through the diagrams
provided, etc... (IE: They didn't seem to make a lot of sense. What I
was seeing for CDP neighbors didn't jive with what I was reading on the
documentation.)

I need to find a resource which uses similar documentation, etc... so
that I can get through this part of the exam. If you would rather not
share your opinion in public, please email me directly. I'll keep
off-list comments in confidence. I just really need pointed to some
decent resources for this. (Make your own labs doesn't really seem to
work for this type of problem.)

Unfortunately, travel and expensive training options are not viable for me.

Thanks in advance for any guidance on this.
