I was a curve breaker in college. These courses are fantastic for filling in the missing details left out to rehash the basics for everyone else and what I've forgotten decades later.
Ironically, when people asked to study with me, they didn't get why studying for an hour each the 3-4 nights preceding an exam was crushing their cramming the single night before, so they would get frustrated with me and leave. Or I was doing spaced repetition before that was a thing.
Which is to say motivated sorts can have trouble finding peers willing to stay focused.
Spaced repetition has been a thing for a really long time. Were you in college +/-1900? Depending on where the line is drawn for spaced repetition, it could be claimed to have been discovered initially from roughly 1885 to 1932.
