I'm concerned with the shear difficulty of qualifying for Master Classes, especially for Claude, now that Wyvern Lord also requires C in Lances, according to u/iamRussFrushtick. Upon closer inspection however, E to C only requires 300. Compare this to E to A, which needs 1320. So, I recon that Claude will manage to reach C in lances, by the way of weekday lessons, before the rest of the requirements.
