Russian lit was never part of my highschool reading. Freshman year was Greek classics and Shakespeare, sophmore year was more Shakespeare and Romance. Junior year was classic American lit, and senior year was Norse mythology and british lit. I diverged from my friends and decided to take the non-AP English classes junior and senior year. I would have been reading non-fiction in AP English Language and books by Bronte and Dickens for AP English Literature. I'm don't think the IB courses covered Russian lit either although my school didn't offer IB.
My liberal arts classes in college didn't involve Russian lit either. My freshman year English I and II classes were very unserious, we read Philip K Dick and a (somewhat distasteful) book by the current governor of Maryland. I could have taken a Russian lit class but instead decided on Appalachian studies which was surprisingly interesting and probably helped shaped some of my politics. I did read A Day in the Life while I was taking summer classes. Admittedly, I was on Adderall at the time which led to me reading at a rate that matched when I was a kid and was tearing through books faster than I could get to the library. I listen to a lot of audiobooks now and miss when I had the attention span to actually crack a book (or at least use a kindle). I've got a copy of Crime and Punishment in my queue but I've been reluctant to start it.
