At this time 50 years ago we were a couple months into the school year, the first quarter having been completed and report cards issued, I suppose, and there were three games remaining in the football season. So how did you feel about being a "senior"? If not in 61-62, whatever year it was that you were a senior?
Personally I don't recall feeling much one way or another. King of the hill? Doubtful. Glad to have one year to go? Dunno. Sad that it would soon be over? Doubtful.
Was it really an achievement to have made it into the 13th year? Let's face it, much of the drill is simply to move on to the next year. We didn't have to pass any competency test other than passing grades, weren't required to climb a certain hill or run faster than a speeding bullet. Call me a realist or a cynic, either one, and if you beg to disagree with the theory, send an email to firstname.lastname@example.org and let's discuss it!
Presumably everyone is happy to have made it through high school and research tells you that it's one of the milestones to financial success in life, but the feelings of being in the year itself? Probably empty for the most part. And now maybe a greater memory than the reality was. What do you think?
