    Q 1 part iv) is badly worded... it says "the number of students who gained exactly grade C was the same as the number who gained a grade lower than C"...

    "a grade lower than C" sounds like a D

    it should say "whose grades were lower than C"

    anyway you read off the number scoring below 27, double this number and read off the score for this new number.
