Test Scores

Goal:

Tell the user their grade! Use double variables to allow for decimals,

Steps:

1. Write code to ask the user for their test score.
   Your program MUST allow the user to enter a test score that has a DECIMAL, e.g. 75.5
2. Give them a different message according to their score.
   Example, for a good score: "Wow! You must have studied really hard for that test!"
   
   HINT: Think about how you would convert a String to an int and use SIMILAR code to convert their test score to a double.
