<p>See… in my precal high school class, I didn’t even need the credit so basically it was just a blow off class. I slept everyday or did something else or skipped to go to my CS class. In the end, that didn’t hurt me in any way. I learned all the math I really needed from SAT and ACT prep tests, physics classes, and the beginning of my calculus class (the teacher gave us some simple overview homeworks in the first week or so). If I ever needed anything more than that, the internet is full of resources. I also did pretty much the same thing with my Algebra I and II and Geometry classes as they didn’t interest me and neither did making good grades in high school much at the time. In my experience, precal was a lot of stuff that I never really needed to know, and if I ever did need to know, I could just look some stuff up on it and see how to do it if I needed to know in order to do a problem. Using it a few times in a problem helps me to remember it.</p>
<p>I say go ahead and do Calc. 1… if you’re comfortable enough in your ability to self-study some concepts that you may not know of and may need in the future. If you’re not so sure, just sit in or even take a summer class, it can only help your GPA anyway.</p>
