You’ll be fine. Most Fry Scholars do all of these programs (except maybe IFS), and none of these things individually requires that much work. You’ll have to go to a few events for the scholarship, take a stupid class for Hudson and Holland, and take a blowoff 1 credit class for the KLLC each semester. Other than the extra classes for the KLLC which will not take much of your time, it’s just like living in any other dorm.
I did the ACE program last year, and while it is a decent amount of work for the classes, almost everyone gets a good grade in C106 and K204. These sections are also not harder than any other section of C106 or K204 (and I would argue it’s actually easier to get a good grade in C106 and K204 vs the regular versions, especially K204). All of the outside events for ACE are optional, and they usually only have 1-2 a month that don’t last that long anyway.
Why are you doing IFS? It won’t cut into your time for other classes during the semester because it’s before everything else so it shouldn’t be a problem, but what’s your reason for taking it?
