Did You Know?
A ruler makes straight lines, while "straight A's" means getting all A grades! Rulers have been used for thousands of years - ancient civilizations used measuring sticks. The modern ruler with inches or centimeters became standardized in the 1800s. The letter grade system (A, B, C, D, F) was developed at Mount Holyoke College in 1897. A 4.0 GPA means all straight A's!
