I get the whole senioritis thing. I do not remember much from HS but clearly remembering having accepted a job at the start of spring semester Senior year in college (engineering). I pretty much put the semester on auto pilot but likely had some easier electives saved to make my grades tolerable.
My twins have a serious case. I think the feeling is like a marathon where you go hard almost the whole way and when the end is in sight, you just want to finish. They are in cost mode with only four weeks left to go, IL starts mid-August.
I told them to get it out of their system now because when they start t UA in engineering the going will be tough and they need to be on their “A” game
