Well, at early Level 2 I couldn't do even an Exa young (although that may have been possible later in level 2, but I didn't try again until level 4).
Tony has been doing quite a few Exa Doms and I know he got to Level 5 last night, but he hasn't tried a Guard as they are lower than Doms
He couldn't do alpha tho, even in the latter stages of Level 4.
I'll ask him to add his info on here.
