did you ever stop studying the things that not useful ?

well, you cant have too much knowledge, so i would not recommend that, worst if it will affect your grades in school.

Yes. I stopped studying alot of things that we do not use in our every day lives. There is no need to keep studying it if we are never going to use it again. I like to learn new things and useful things that we do need.

interesting topic Perhaps it would be good to learn about as many things as possible while in school. Besides, it would not be wise to perform below acceptable in the metrics (exams). With my self in the situation, I would take time to learn extra stuff that I believe may become useful. Cheers
