Workflow courses

[Ruby Gregory-Gagne]

Recommendations please...
 
I am planning to take workflow courses this fall (BC 600+BC 601).  We are
currently at 4.0B, but may upgrade to 4.6 some time next year.
 
Is workflow that different between the versions?   The course length has
been extended by 2 days for 4.6B.
 
I was going to take the 4.6B courses but if I start with a 4.0B system will
I be able to apply the knowledge from the course?  Will there just be some
features missing?
