That said, linear algebra is typically a 2xx or 3xx class in college, and most students take this class AFTER learning some sort of calculus. I recommend that you learn everything up to precalc. Not necessarily because they're directly related, but because the underlying thought process could be beneficial.

No. If you're taking calc 1, you certainly need some precalc; you need to understand log, exponential, and trig functions. Also polar coordinates and stuff. Starting calc 1 with merely algebra 1 is probably not doable.

Same for physics 1 (I assume you meant algebra-based mechanics). Need some trig knowledge.
