Discounts for CFA registration

Anyone has any idea how CFA institute calculates discounts offered while registering for its exams? Also are there any offers going around - While I tried to register for CFA lv 3, there were two boxes mentioning “Offer Code 1” and “Offer Code 2”. I have received none and not sure what they are? For someone was asking in forum - Looks like we will have to answer a bunch of questions before registering for the exam. It is mandatory, otherwise we are not allowed to register for lvl 3.

I think the CFAI calculates the discount automatically and it’s based entirely on how intelligent/how likely to pass the exam they think you are. If they’re still asking you for the full price I’m not sure I’d even bother taking it.
