It's stated that Snape, McGonagall, and Slughorn required a minimum 'E' grade for students wishing to proceed to their N.E.W.T. level D.A.D.A., Transfiguration, and Potions classes in 6th year (although when Snape was teaching Potions he accepted nothing less than 'O'), but is it ever stated if Flitwick and/or Sprout required 'E'-minimum for N.E.W.T. Charms and Herbology? If they did, than Ron would have 'E's in both of those subjects as well. 14:10, 26 May 2009 (UTC)‎
