Integer.TryParse(Console.ReadLine(), test1)
Console.Write("Enter grade for test 2: ")
Integer.TryParse(Console.ReadLine(), test2)
Console.Write("Enter grade for test 3: ")

Console.Write("Enter grade for test 4: ")
Integer.TryParse(Console.ReadLine(), test4)

Dim finalGrade As Double
''calculate finalGrade
finalGrade = test1 * 0.15 + test2 * 0.25 + test3 * 0.3 + test4 * 0.4
''print the final input

End Sub

End Module
