+// QUESTION 3
+// Imagine you are a teacher and your students have taken a test.
+// The tests are marked with one of the following grades: A+, A, B, C, D, or F
+// You want to find out the average score of the class as a number.
+// For this, you can assume A+ is worth 100, A is 90, B is 80,
+//      C is 70, D is 60 and F is 50.
+// Write a function which,
+//      given an array of grades (which are either A+, A, B, C, D, or F)
+//      returns the average score of the class as a number
+
+
+// QUESTION 4
+// Months are represented as three-letter strings
+//      ("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul".....).
+// Write a function solution that, 
+//      given a string S representing the month
+//      and an integer K, 
+//      returns the month of the year that is K months later.
+// For example,
+//  Given S = "Mar" and K = 2, the function should return "May".
+//  Given S = "Dec" and K = 23, the function should return "Nov".
+
+// QUESTION 5
+// The month and year are represented by an object,
+//      For example, { month: 'Jan', year: 2023 }
+// Write a function which,
+//      Given an object representing the month and year (like above)
+//      and a number n,
+//      returns the month and year which is n months later 
+//      using the same type of object
+// For example,
+//  Given { month: 'Jan', year: 2023 } and n = 25,
+//      the function should return { month: 'Mar', year: 2025 }
