What am I doing wrong?
This code is suppose to initalize the variables using a constructor while instantiating three Student objects. The Student objects should each receive five arguments including the student's first name, last name and three decimal value scores. The scores represent the grades they receive on exams. The maximum number of points is 100. The objects should calculate the average test scores for the three exams, output the average test scores and a letter grade for the average test score for each student. >90 = A, 80-89 = B, 70-79 = C, 60-69 = D <60 = FCan anyone 1. help me sort this mess out? Thanks!
