A Dreadful-gradedW.O.M.B.A.T.
- "The general standard of this homework was abysmal. Most of you would have failed had this been your examination. I expect to see a great deal more effort for this week's essay on the various varieties ofvenomantidotes, or I shall have to start handing outdetentions to those dunces who get D's."
- —Severus Snape tofifth-years inPotions[src]
Dreadful was one of the three failing grades, out of six grades overall, in theOrdinary Wizarding Levels,Nastily Exhausting Wizarding Tests, andWizards' Ordinary Magic and Basic Aptitude Tests. It was the second lowest mark, immediately below 'Poor' and immediately above 'Troll'.[1]
Advancement[]
If a student was given a 'Dreadful' grade on theirO.W.L. test, they could not continue on with that subject as aN.E.W.T. class. This was the same for the other failing grades: 'Poor' and 'Troll'.[1] It is unknown if a student could repeat the subject if they received a 'Dreadful'.
