In the play against the clock mode, you have 60 seconds to solve as many inequality expressions as possible.

is calculated by subtracting the player's total number of incorrect answers from
the player's total number of correct answers.
For example, if a player had 27 correct answers and 5 incorrect answers, the
player's skill level rating would be 22.
Skill Level Ratings
