Research suggests that the time a student spends studying for an exam is positively related to the grade that student receives on the exam. However, last week, you took an exam without studying and got an A on the exam. What should you conclude about the relationship between study time and exam scores

Answer: Exam score is not the true test of knowledge, and the time spent on studies cannot be determined with exam score

Explanation: Exam is only the test of your assimilations during class hours. If a student should score an A without studying for the exam, it simply means his assimilations on that subject is very high during class hours, more than the ones who spend hours to study the subject after class. What most lecturer wants from a student is what he has thought and not what you feel. So the assimilations of a student during class hours plays major role in the exam Score
