New member from Idaho

Title says it all. Taking the plunge into trucking. Applied to Prime Inc and was accepted and start my first day on March 4. Going thru their school and taking suggestions and getting my CDL permit here in Idaho. With that in mind I wanted to ask what your opinion is on http://www.thetruckersreport.com/truckingindustryforum/private.php?do=showpm&pmid=799824 as a tool to help study and practice for the test, and how close is it to the actual test?
I am also downloading the Idaho CDL Manual and reading all 229 pages of it.

I'll be honest I am little nervous about this change. Not sure what to do with my things at home. Renting room and using it as my home base and a place to keep both my vehicles. Any suggestions would be helpful from someone who has made the transition.
Thanks and look forward to your comments.
