Dasha, Best advice is just don't worry and go on with your life and enjoy your summer. Worrying won't help expedite things one bit or help avoid RQ or ... If you will get an RQ you will get one, and if you will get an Oath you will get that too. If you never traveled any where you might still get an RQ, you might travel 100 times a year and then get an oath within a month of your interview. they might like your blue eyes and get you an Oath or they might hate how crooked your teeth and put you at the bottom of the heap. No one knows how these things run. For all I know, they probably scatter the applications on the ground, grab a chicken, cut off its head and throw it in the room, and wherever the chicken dies, that's who becomes a citizen and they then have chicken barbeque for lunch (if you watch southpark, you probably know that episode)
Unfortunately the citizenship system is setup to be extremely biased and lacking any equality. They want to delay us from obtaining citizenship and in addition they are making laws that strip you from citizenship easily, so it is a losing battle. Folks from Toronto area are known to have much faster applications. Calgary has like 18 ceremonies scheduled every month while Edmonton only would have like 5. Welcome to Canada.
