With the old CPE portal you just used to select if the CPE was Group A or B but apparently many members weren't smart enough to select the right option.
With the new portal they created a decision tree style system to help guide members by asking them questions. The answers to those questions will ultimately decide if the CPE is logged as Group A or B. The final question in the Group A flow being to what domains does the CPE apply?
I don't like the new system but then I know the difference between Group A and B CPEs.
