Maybe it works for people who are trying to learn PART of a topic, but for people who are working seriously, this website SHOULD BE AVOIDED.
I missed a unit of trigonometry and my teacher told me Khan academy should help me get caught up. He was planning to help with me with parts of it, but expects me to learn the majority of it on Khan.
I got on. Looked through the trigonometry lessons. Looked through the precalc lessons. Searched the videos. Scrolled through dozens of options.
THERE WAS NOTHING.
According to my textbook AND teacher, this was the most important unit in trigonometry, and Khan had NOTHING on it.
The website is awful. Stay away.
