I have just upgraded from V 10.5 to V 12. My associate learned the V 10.5 from the Learning Series CDs for Foundation I & II that we were provided, but I did not (she's moved on, so I'm on my own). Should I learn the Vwks basics from these disks, or should I get the newer Core Concepts training disks instead? I want to be able to move on to the Landmark CDs for V 12 ASAP, but I need to know that I have the correct basics under my belt first.
