I finished my algebra, clicked on the top left 'khan academy' button, which takes me to https://www.khanacademy.org/profile/Epeon/courses, and I scroll down, except the biology course i usually took is just gone. I go to courses and add biology library and high school biology since i can't remember which i did. The purple colour of Biology library makes it the winner, but the course has reset. The exercises aren't done, and the text lessons aren't read. What do I do?
How can we help?
