Academic ghostwriting is when a person pays someone else to write their school work, like essays or papers, instead of doing it themselves. It's like asking your big brother or sister to help you with your homework, but instead of helping you, they do the work for you and you pretend it's your own work. This is not a good thing to do because it's cheating and dishonest. The reason people do academic ghostwriting is because they might be too lazy to do the work themselves or they want to get a better grade without putting in the effort. However, this is not something that should be done because it does not allow you to learn and grow as a student. It's really important to do your own school work so that you can learn new things and become more knowledgeable in the subjects that you're studying.
