If you are bored, then you’ve got a great opportunity to cultivate your own sense of what is interesting to you. Show up, do your classwork, etc and finish out the year, but don’t let your time get sucked up by stuff that doesn’t interest you. Instead, give yourself a little space to think about something (or things) new that you’d like to try, something that suits your personality and style.
Decide that you are going to absorb everything you can about a particular field (fashion, a period in history, how gadgets work, psychology and what makes people tick, whatever, so long as it is exciting to you and holds your interest.
Do you volunteer at all? Try that. Try doing it with a population that interests you (elderly, poor, health-impaired, homeless).
As far as things to do with friends: karaoke, start a cheesy band (you could even do it with improvised instruments from the garage or whatever), have game nights or tournaments of some kind, people watch and make up stories about their lives.
Boredom is (quite obviously) a sign that you need change, but it’s also a sign that you need to get quiet and put your imagination to work.
