Okay, I've read over this entire thread and I'm still a bit confused.
The way I'm understanding it though...courses retaken at the SAME school must have the same course number and prefix as when you initially took it.
Retakes taken at different schools can still have different course numbers and/or prefixes as long as the credits/content is the same. (no change in policy here)
So the only real change in the policy is the first sentence about retakes taken at the same school.
I sure hope this is the case anyway since I've spent the past 2 1/2 years retaking 20+ classes at different schools.
If they weren't accepting those anymore, I think my head might literally explode.
