AP®︎/College Calculus AB & Linear Algebra Length

Hi all,

I'm very new to these courses at Khan Academy, I was hoping to find some references to see a rough estimate of how long it would take to complete these courses. For instance, the total video hours or an estimate of how long each of those courses would take. 

I'm hoping to finish calculus first and then move on to linear algebra. 

Any help would be greatly appreciated!
