Realistically, how much, if any, free time like this do you have on a weekly basis? Thanks
4.3 minutes of free time per day is allocated.
And you must use it!
Seriously, it will vary by week. Thayer weeks are very tight. And some weeks the moons align and there is more time. And some when they align badly (Thayer week + SAMI + in ranks inspection ++++)
It will also vary by academics, your particular classes and how well (or not) you are able to handle them.
Then factor in company, club, or corps squad athletics. They vary significantly in time commitment. When DS is competing in club athletics, roughly 75% of his Saturday & Sunday's are taken. Good news: he has autho's to miss drill on Saturdays, and gets off campus. Bad news: He misses normal cadet down time on Saturdays with no drill & Sunday. Corps squad is even more extreme.
You will have breaks at times between classes, and the occasional light day. Most cadets find time to work out in some form, though for most it comes via company athletics plus whatever they chose to do on the weekend.
Sat evening, and Sundays are nearly always free.
If you use your google fu, you can can find the "Buff card" for the current academic year which shows the exact schedules.
