<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">school mark</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for grade that I've seen before include "one of the entertainment moguls" , "Particular level of rank, quality, etc" , "Rank or status" , "Degree" , "School mark" .)
