Can someone help me with this search? I refer to the tutorial.
I can't see how they decide which is an alpha and which is a beta.
To me all B, C and D should all be beta values, but they are not.
Same on the next level. All values should be alpha values but they are not.
I am hoping that we don't get an alpha-beta question, this has to be one of the most difficult concepts of the whole module. I've looked at so many examples and I still don't fully get it
