Write a Student class which keeps track of grades and generates a final mark. You should store:

-3 quiz scores, an array of int between 0 and 20;

-1 midterm score, an int between 0 and 50;

- 1 final score, an int between 0 and 100;

- the overallScore (double) and letter grade (char).

also create the appropriate accessor and mutator methods.

Student should also include the methods:

public void calculateOverallScore() { }

Quizzes are worth 15% of the grade,

Midterm is worth 35% of the grade,

the Final is worth 50% of the grade.

public void finalLetterGrade() { }

100 ~ 90: A

90 ~ 80: B

70 ~ 80: C

60 ~ 70: D
