So I'm pretty shit at math, did average in school but that was 10 years ago, I didn't value an education back then.
I'd like to improve with the goal of getting to college level, Khan Academy seems like a great place to learn, but they have quite an overwhelming selection, I'm not sure what courses to do and in what order. So many of the courses seem repeated, I just want to take the most efficient (and obviously beneficial) route.
I've looked for syllabuses online but couldn't find any guides, can anyone advise on a path going from Arithmetic to college level Calculus / linear algebra?

Start at precalc if you remember some algebra then do trig then calc AB and BC

What you need to learn in order is:
1. How to operate with integrer numbers (eg (-5) + (-74) =)
2. How to operate with rational numbers (add, subtract and multiply fractions)
3. How to operate with irrational numbers
Once you're done move to algebra. You could do the algebra course on Khan but imo if you're serious about getting good at math you should just buy a well-reputed textbook and do the exercises.
Then learn high school math with Serge Lang's Basic Mathematics textbook.
Once youre done, good luck on the SAT

I am in the same boat and I am going to start from the early math/kindergarten course. Reportedly it only takes a few days to get to Pre-calc from there, I am just going to deal with it rather than potentially miss some important fundamental

I think you might be missing a few steps there.

I’ve been doing the arithmetic course to catch up on some topics, but it’s starting to get extremely boring because it’s so painfully simple, but I don’t want to accidentally brush over something important that I don’t fully understand. Operating with rational numbers is definitely something I’d need to brush up on, I guess that would be in the arithmetic section too, so I’ll stick it out. I guess after that I’ll do pre algebra, algebra basics, algebra 1 and algebra 2 and check back in after that. I’ll look into some textbooks too, thanks for the suggestion.

Just don't spend too much time on precalc. Especially trigonometry more or less becomes trivial once you learn about complex numbers

Everybody uses trig, nobody uses imaginary boogers

Paul's notes is the best.
https://tutorial.math.lamar.edu/
he has algebra up through diffeq. He also used to have linear algebra but took it down (I think he got a textbook deal). But you can still find it in pdf.
He's short on actual problems though so use a textbook with solutions manual or maybe a site like practiceproblems.org which is archiving problems on youtube if you want video explanations.
khanacademy is goyslop imo
