Question

A Class assessment is based on Three Examinations, Homework and a Final Project. The weight for each category is as follows: Ex 1, Ex 2 and Ex 3 Weight 45% of the overall grade, Homework Weight 25% and Final Project Weight 30%.

Write a C# program ( Console or GUI ) that prompts the user to enter the three examinations ( ex1, ex 2, and ex 3), homework and final project grades then calculate and display the overall grade along with a message, using the selection structure (if/else). The message is based on the following criteria:

• “Excellent” if the overall grade is 90 or more.
• “Good” if the overall grade is between 80 and 90 ( not including 90)
• “Above Average” is the overall grade is between 70 and 80 ( not including 80)
• “Average” if the overall grade is between 60 and 70 ( not including 70)
• "Poor" if the overall grade is less than 60 ( not including 60)

//Main method

public static void Main (string[] args)

{

//Declaration of variables

double ex1,ex2,ex3,homework,finalProject,totGrade=0;

//Prompt and get from users

Console.Write("Enter the Grade for Examination 1:");

ex1 = double.Parse(Console.ReadLine());

Console.Write("Enter the Grade for Examination 2:");

ex2 = double.Parse(Console.ReadLine());

Console.Write("Enter the Grade for Examination 3:");

ex3 = double.Parse(Console.ReadLine());

Console.Write("Enter the Grade Homework:");

homework = double.Parse(Console.ReadLine());

Console.Write("Enter the Grade Final Project:");

finalProject = double.Parse(Console.ReadLine());

//Calculation of grade

totGrade=(((ex1+ex2+ex3)*(0.45))+(homework*(0.25))+(finalProject*(0.30)));

//Conditions

if(totGrade>=90)

{

//Print statement

Console.Write("Excellent:Your Grade is {0}.",totGrade);

}

else if(totGrade>=80 && totGrade<90)
