Why is that in high school, Trignometry is often not a course, but in college, it is? I remember in high school, after taking Geometry in Freshmen year, I took Algebra 2 in sophomore year. Then in junior year, i took Pre Cal, and then Calculus. I just took a placement test at a community college, and it shows that my Trig score is not ready for Calculus. The counselor asked me if I wanted to take two steps back to get Trigonometry, or if I wanted to take only one step back to take PreCal. My scores show that I should take Trigonometry, but because I took AP Calc in high school and Calc in college( that I failed, one of the reasons is that I had a really shaky math foundation), she is willing to let me take Trigonometry, Precal, or Calculus. I don't want to waste a semester taking Trigonometry. Isn't Trigonometry included in Precalculus? I remember that in high school, there was a lot of Trigonometry in my Precalculus class. Why is there a separate class for Trig in college, but not in high school? Should I take Trig and PreCal or does Pre cal include Trig? I know I am not ready for Calculus, because I failed it twice (mostly because once because I was online too much, and once because I had too many units so I didn't have enough time to do math, but I remembered that I had a very difficult time when I really did sit down to study, because I didn't have the fundamentals and foundation of pre cal. I didn't struggle to derive equations; that was easy and straight forward. I could do that in my sleep. I did, however, struggle to manipulate equations, isolate variables, do trig functions on related problems, set a equation single variable, simply and factor equations, etc. Basically, I forgot everything but the Calculus.
