Just my general opinion: science classes are going to kick butt, no matter if it’s UA or somewhere else…for a reason: weeding out those who are not capable and/or under-dedicated/under-motivated. So, @seaotter17, plan for the worst and expect the classes to be difficult wherever you land, and work your butt off to maintain a stellar GPA. The fact that some colleges’ test score quartiles (esp at UA) have been rising over the years doesn’t help either: expect top-notch students in all of your core classes, who are all working hard for A’s. Welcome to college!
