Studying time is proportional to exam scores. Spending more days, such as four to six days; exam scores are from 80% and above to more than a 90%. Individuals who spend six days receive a 90% and above. Anyone spending more than six days or more than a week; recieve a full average. Those achieving a full score, remain constant for those who spend more than six or seven days preparing.
