## Studying

In a survey of studying methods, students who studied based on the unit questions scored the highest (85.3%), though less than a third of the class used this method. There was no difference between reviewing notes once or multiple times. Students that could only dedicate a fixed amount of time understandably scored worse than the other study methods.
