For this check-up, you can choose the grade you would like to earn.
For a C (70-79) -> You must complete questions 1-6.
For a B (80-89) -> You must complete questions 1-9.
For an A (90-100) -> You must complete the entire checkup.
To earn the grade at each level, you must do quality work. Quality work shows a strong understanding of the math, uses accurate mathematical strategies, and provides clear explanations.
It is important to understand that you are not guaranteed the grade you are attempting to earn. Choosing your task is just your starting point.
