DANTES exams question (specific subjects)

Guys & Gals, I'll be taking the following DANTES exams:

Astronomy
Here's to your Health
Principles of Public Speaking
Ethics in America

I already picked up a guide for Here's to your health, but haven't on the other three. Does anyone have links / hints / tips for the others ?

Oh - time frame.. I intend to take these sometime this summer, to give me plenty of time to prepare.

Thanks in advance

 

Here is a link to the Fact Sheets.
