In high school I had some issues with my geometry teacher in sophomore year and I ended up never taking any math courses so I ended up with twice as many science credits as math. Right now I'm going to college for the first time(this spring semester at a local community college) and classes start in three days... I asked the math department if I could be exempt from taking pre-calculus and they said I could take credits by examination. I've been studying a bit on my own and there are certain things I have a strong grasp of but since I've never taken an actual precalculus course I'm not sure what I must know for the credit by examination. I know my community college is very lenient with test scores so I only need around 55% proficiency but I'm still feeling a bit unsure. Some notes: I scored 96 on the math a regents, 94 on the geometry regents, and I scored 630 on the SAT math with no prior practice(scored 1810 composite). It's suffice to say, from my own observation, that I may perhaps be quite good at test taking but I'm not sure if that will be enough to take a test for a subject I never studied in school(mostly referring to the trigonometry part). Also, the grades I received in the first three years of highschool were horrible(average 72) because I was going to a far away magnet school, depression, etc. In my last year of highschool I transferred to a local high school and managed a 96 average easily. My depression has subsided but the academic pothole that is reminiscent from my bad days still haunts me. Should I take the credit by exam(it costs $15 to take the test, if I pass it equates to 3 math credits although I'm guessing most people come into college at least a year ahead relative to where I am in terms of mathematics[e.g people take precal sophmore year, AP calculus BC in junior year, and then senior year of highschool they take differential equations and etc]) or should I take a semester course of pre-calculus? As I said, this upcoming spring session(starts on the 28th) is going to be my first time in college and I wish to someday be a physics major. Money really isn't an issue for me so when I transfer I can go to any 4-year college I'm accepted into(my parents make over 200k a year). Also, if it is the case that my best plan of action is to take the credit by examination, what is most important for me to know? I ask this because I was told by the math department at my cc that this is the last week I can take the exam.
