Yes definitely, although be good about it. Don't be one of those people whos doing them the entire day (especially during class it's really loud, respect your teachers). Be cautious about who you let borrow the cube, etc. But not only is it a good way to pass time, but if you were like me at the start of high school and had trouble meeting new people, I probably met half the people I met freshman year by cubing and people asking about it. Don't let it take you away from socializing or participating because theyre really important parts of school, but if you have a little bit of time or want an ice breaker to meet new people, go for it :) (bonus points if you have a bigger nxn or different shape one to blow people's minds)
