I took algebra 1&2, geometry, physics, and ap stats. I got A/Bs in those classes but it’s probably not comparable to a college setting in terms of difficulty.
Taking 16 during a quarter isn’t really an option for me since I need to get my pre-reqs done or I may fall behind. I also think taking the 16 series wouldn’t count at all for my major and I’d have to take all of 17 series anyways right after.
However I am already looking at plans to possibly take a summer course if my community college offers a substitute and definitely putting in extra time to learn calculus (more efficient studying/office hours/tutoring)
