Hi I was wondering how long it would take to self study math using Khan Academy and supplement the website with a self teach book from Geometry through Calculus. I am a sophomore in high school and I am hoping to take the CLEP exams for Calculus and College Algebra after senior year. I was wondering if it would take a couple months or what and if anybody else did something similar to this, also some suggestions would be helpful. Also lets say I study about 10 hours a week. Thank you much!!!
