Why is it iam ajn instead of kiam ajn?
I would like to know too, because in the sentence "Whenever I run fast, I am proud of myself," the correct answer was Kiam ajn... and I was marked incorrect for Iam ajn... So here I used Kiam ajn... and was marked incorrect again!
As was I. :?
The ĉiam kiam construction is entirely out of the blue as near as I can tell.
