/*
	Complete the getGrade(score) function.
	It has one parameter: an integer, 'score',
	denoting the number of points Julia earned on an exam.

	It must return the letter corresponding to her 'grade'
	according to the following rules:
	If 25 < score <= 30, then 'grade' = A.
	If 20 < score <= 25, then 'grade' = B.
	If 15 < score <= 20, then 'grade' = C.
	If 10 < score <= 15, then 'grade' = D.
	If 5 < score <= 10, then 'grade' = E.
	If 0 < score <= 5, then 'grade' = F.
