Yeah this is a bit ridiculous and likely to get worse once 7 and 9 results come out. Unless magically a bunch of spots open up when people start changing whatever exam they originally registered for.
Unfortunately we are competing with other organizations as well. In theory if the CAS extends the window to make room for us all to take the exam, will that extend the grading process? Just puts us back in the same position as this sitting and shortens the study window for the fall.
