Just to share some info with the rest of the groups.  After a discussion with a mentor as part of the Oracle 11g - Database Administration course, they were able to tell me in which order the modules should be studied.

Basically, if you click the details link on each module in the training plan, you'll be able to see a reference which looks like this - od_odas_a01_it enus

In this example, the number 01 means that this would be the first module, 02 the second and so on.

Just thought it might be useful moving forward.
