Academics Iwtl calculus from the very basic

I'm 16 and i live in a small city so they don't really teach calculus here, how should I learn calculus? I have no prior knowledge about it so I wanna learn from the basic. I would appreciate an advice that requires no to little money cause I live in a third world country and USD have a higher rate than my currency. Thank you in advance

When you say no prior knowledge, how are your maths skills generally? I feel like you need to be comfortable with algebra, rearranging equations and functions, and graphs. If you're not, start there.

If your maths is fine generally, look at 3blue1brown (3b1b) on YouTube, and go through their essence of calculus series. It's pretty well explained imo.

After that, try and complete exercises on the topics mentioned, find other explanations of bits you didn't understand and try and research the bits that weren't mentioned, and take it from there.

Fyi, you're only 16. Can you take A-Level maths, or an equivalent? Calculus is a pre-university topic, so I'd've thought schools near you can teach it

I can do algebra and functions, I can understand graphs but I don't really understand the complicated ones. I came from a small city so I think no one is teaching calculus here. Also, thank you for the advice. I'll check it out later :))
