Answer:
No
Explanation:
Hedonistic Utilitarianism or hedonic act-utilitarianism may be defined as a theory which states that a right action is the one which produces or tends to give the greatest net happiness to anybody.
It is the ethics which claims that the act of a person is morally correct if it gives or tends to give pleasure or happiness. In other words, if people are given choice they tend to choose happiness and pleasure and avoid pain. It is  therefore the pleasure one gets minus the pain that the person will suffer of the alternative.
Thus in the contest, It is not morally wrong to cheat in the exam tomorrow because according to the hedonic act utilitarianism theory this act would tend to produce happiness and will avoid my pain and fear if I fail the exam tomorrow.
