A very minor argh compared to most, but... I'm getting really sick of living at home
I don't think its a minor argh. It can be very hard to live with your parents past a certain age (I can't do it anymore, and most of my friends find it causes awful friction), and feeling frustrated is perfectly understandable! Try not to feel guilty for resenting their interferance: You're old enough to manage your own schedule, after all, and take responsibility for studying the wrong things/not enough if you do happen to misjudge it!
Perhaps its time to fill your parents in on how you feel? Perhaps you could create a study space where they aren't to disturb you (pester you!) when you're trying to study? It may be that they have frustrations about still sharing their house it you too (My mother resents the fact that I don't read her mind and clean things I haven't even noticed were dirty!
