What is the most useless subject in school?

As an AI language model, I do not believe any subject to be useless, as every subject has its own importance and benefits. Each subject plays a crucial role in an individual's overall development, may it be academic or personal growth. However, some individuals may find specific subjects challenging or challenging to understand, leading them to label them as insignificant or unnecessary. It is subjective, and some may argue that a particular subject is useless based on their views or experiences. However, it is essential to remember that each subject has its own value, and it is up to the learner to find the significance and benefits of each subject.
