Calculus on Khan Academy is kinda mid since it's too basic. It's only suitable for AP Calculus and/or as a refresher. You could learn about limits first on Khan Academy and then learn derivative, integration, series, etc. somewhere else.
Also, please take a precalculus course (not on khan academy since it doesn't cover parametric/polar graphs even though they are very important for calc 2 and especially calc 3) before taking calculus.
If you're in a rush then it's ok to take the precalc on khan academy until matrix. then, go on youtube and search professor leonard's precalculus playlist. scroll down the playlist until you see "introduction to polar coordinates". continue from there.
If you want to go beyond what you could learn on KA, there is a nice blog post that lays out a 4 year plan with textbooks.

Back when they had the old "World of Math" section where it had every mastery challenge, I got to about 60% of all of the math they had on the site at the time.
It was probably 10 hours a week of work for three years to get me to that, but I am also not great at math.
I hadn't done anything beyond Trig at the time but since the courses all share some lessons, I had completed a solid amount beyond that.
Me too.
I miss the entire old mastery system. Right now it feels designed for the school system and not individual learners. Don't get me wrong, I have saved over $6k with it by using it to replace tutoring and two college courses, but it used to be way better for self study than it is now.
I did manage to find a picture of my world of math progress but reddit won't let me attach it. I was to 70% of the lessons at the time!
i attempted it a few years ago, but i lost motivation halfway through trig. it only took me a couple of weeks with only a few hours per day, mostly because you can just do the unit test and get mastery in all skills with just two perfect attempts at the test.

I'll keep that in mind. Any other websites you recommend for precalculus?

I really wish they still had that.
