It was pretty different here, since both my wife and I did our undergraduates in Israel, where it worked like most of Europe - you submitted your matriculation exam results and your psychometric test results, and waited. My wife had her high school test results from the USSR (which has just come apart), and those were accepted instead of matriculation exam results.
I applied to college after finishing my 3 years military service, and my wife had just immigrated, on her own, from the USSR (her family came separately, 5 months later). So it’s safe to say that college applications stress was seen from a very different perspective than a kid who is still a high school senior. Moreover, based on our applications, there was little chance that we wouldn’t get into the programs to which we applied, so we applied to two universities each (there were only 6, in any case).
My wife and I (mostly I) learned the college application system in the USA alongside our kid. Because we only started learning the process relatively late, and because our kid’s high school (and the community) have eschewed the attitudes that are almost ubiquitous among people of the same SES, both our kid and we were blissfully unaware that we should all be stressing out about admissions to the very lowest acceptance colleges from the time our kid was in middle school (or earlier).
Moreover, our kid was far more involved in social activism than in college admissions, so we really did not even think about colleges until she was in her second semester as a junior (except a visit or two). Since the state flagship was excellent and a safety (and extremely affordable, since my wife worked for the same system), we weren’t worried about whether our kid would be able to attend a “good university”.
So her college admissions journey, at least until her senior year, was pretty typical for most USA students, though not for kids of her SES, or what seems to be the case when seen through the lens of CC.
Her journey as senior year began was not the typical college admissions journey in the USA either. But that is a different story for a different time.
Interestingly, both my wife and I did engage in ECs in high school. However this did not go on college applications in either country, and the concept of ECs as something that is done “for college” was entirely foreign for both of us. So we did make sure that our kid participated in extracurricular activities, but they were based on what interested her and enriched her education (or life).
