Just finished my KN degree with all A's here is a tier list of difficulties of classes to help people format their schedules.
S - None
A (you need to study a good bit) - Anatomy 1 + 2 (Lab section is pure memorization and is pretty easy content wise just fast spaced and how well you can memorize, Lecture is similar but more application based, personally didn't find it too difficult largely depends on how well you memorize things)
KN 261 - Similar to anatomy, good amount of memorization + application, however questions on exams are worded strangely sometimes but she does give back points if pointed out.
B (You need to study a bit) - KN 352 - Little memorization and mostly tests your understanding of topics Exam can be hard, but there are a lot of supplemental assignments to help your grade.
C (Not too hard, but not easy) - KN 362 - Exams are slightly difficult however, you get a double sided cheat sheet, spend time on your cheat sheet and exams are easy. Class is largely based on Exams so don't mess up.
KN 445 - Great class, very interesting, not difficult since by this point you know most KN topics but good amount of weekly assignments and projects.
KN 372 - Exams aren't bad, not too difficult
C (easy little to no studying required) - KN 237, KN 336, KN 361, KN 200 KN 245, KN 126, KN 152.
D (show up and you get an A) - KN 100, KN 491, KN 495
Hope this helps people schedule classes, if you would make any changes let me know and if you want further insight in what certain classes are like you can ask. GL with Finals people.
