World Population exam Excelsior

[laughter]

Thanks for your info! I'll do as you said ;-)
Do you also need to know all those formula's or don't they ask them (a lot) on the exam?

Well, I haven't taken this specific exam, but I've done a whole bunch of other UExcels. Generally, if it's listed in the content breakdown, by all means do learn it. Or else you could take the PT/sample questions first to check if it's needed.
