I am trying to learn algebra 2 by myself but I am having some troubles. I bought a textbook and was trying to learn the material just by reading the book and doing the exercises but I couldn't figure out how to do the exercises very well. So next I tried to use Khan Academy to help me understand the exercises but all the problems shown on Khan Academy were too simple and not like the exercises in my textbook. I think what I need is an online course that is similar to an actual classroom, meaning that they presents a video on the topic, show how to solve a few problems, then gives exercises to solve. I don't have any money to buy a course but I would like it to be self paced so I can go as fast as I want through the course. Like I said I can't figure much out by myself, but when I am in math class in school I understand the material presented very well. Any advice or suggestions would be very helpful and appreciated. Thank you.
