Op,
At most colleges, psych 101 is a fairly easy class, is generally an interesting class, and also fulfills GE requirements. So a ton of kids take it’and usually in their frosh year. Many kids who have taken AP psych will retake psych 101 to get the easy A. The class does not get any “easier” by waiting for soph year. The class would still be filled with frosh and repeat AP kiddos.
I guess the only way it gets easier to get an A in soph yr is at huge public unis where 500 kids take it and the grades are “curved” so that only x amount of kids get As. There would be a small benefit of waiting until soph yr, because generally sophs are better at studying than frosh. Just as the game that this rule would apply to any “typical frosh class” that a soph was taking. If you play this game, then what other classes will you have left to take in your frosh year? If there are plenty of other classes to take, then it’s fine to wait.
Others will argue that it’s better to take psych 101 frosh year because it’s better to take an easy and interesting class in frosh year when there might be so much learning how to study in this new environment and will make the transition to college more fun and gentle.
