When you use nested if statements, you must pay careful attention to placement of any else clauses.

Create a switch statement that will test the value of a variable named score . If score has a value of 5, create a println statement that will output "Excellent". If score has a value of 4, create a println statement that will output "Great". If score has a value of 3, create a println statement that will output "Good". If score has a value of 2, create a println statement that will output "Fair". If score has a value of 1, create a println statement that will output "Needs improvement". If score does not contain a matching value for any of the case statements, create a println statement that will output "Retake test".

When you create a block, you must place multiple statements within it.
