I'm planning to take physics, chemistry, biology classes at KHANACADEMY.
I'm trying to make a study plan.
So I want to know how long each subject would take to finish.
Does KHANACADEMY show the total amount of video playing hours of each subject or, at least, the amount of minutes each short video takes indicated next to every links to video clips?
I figure that the information would help me make weekly and monthly plans ahead.
