my path will end up being College Algebra, PreCal 1, PreCal 2, Calculus 1, 2, 3, Linear Algebra or Diff Equations

My recommendation for anyone who was halfway decent at math in high school is to review all the math you've ever learned before taking the placement test. The "standard" path gets a student to pre-calc by senior year of high school, so a student who can retain those skills can place into Calc 1 and skip those other classes.

Most students forget everything from high school. If you struggled with math in high school or had bad teachers, then it's worth retaking algebra and/or pre-calc, but otherwise if you were solid on math skills in high school, then it won't take a ton of review to get where you need to be for a calc class. I mean, it will take effort, but review on khan academy is cheaper and less time consuming than going through 3 semesters worth of classes that cover material you've already learned.
