Learning the concepts can be done relatively quickly.

Foundations can take longer as repetition would need to be done over a period of time. Especially for math, it needs to be done consistently before muscle memory allows you to do the problems without having to reference notes or think about it too hard.

As for time frames that would depend on your IQ.

3 years minimum with really hard work (8h/d) seems reasonable (if you can work hard).
