Hi!This is your code without errors!<\/h3>\n

So, I changed somethings, I’ll list them to get clearer.<\/p>\n

    \n
  1. To use “Name” and “Id” in more than one method, it is easier if they are global variables.<\/li>\n
  2. When calling the “test” method you need to pass the values, so in the “entry” method the values are passed.<\/li>\n
  3. The “printData” method is called within “results” to receive the value of “totalScores”<\/li>\n
  4. Also in the “results” method to calculate the value of “percentage” you must divide by the number of scores, which in this case is 3<\/li>\n
  5. \n

    The methods need to be static, just the test method. In the test method, a class must be instantiated to test the class itself.<\/p>\n
