  1. Take Practice Test: On a separate sheet of paper write down numbers 1-100. 1. 2. 3. through 100. Indicate which ones you got correct with + or - . Use the grade breakdown to check your score.

  2. This is the Benchmark Grade Breakdown Grade # Correct A94 - 100(earns Full letter Grade Increases) B 84 - 93(earns ½ letter Grade Increases) C 69 - 83(earns ½ letter Grade Increases) D 59 - 68(Maintains Current Grade) F 0 - 58( Grade May Go Down)
