Depends on your math background. I had none in my day. Do you want to understand it or just answer the questions? Do you want to LEARN it, save it to use later in life or just get through the course? I suggest general math, pre-algebra and a good tutor if you really want to learn it. Then again YouTube may have your tutor right there for you. Good luck. My tutor helped me earn a B in Collage Algebra and I'm very proud of it considering.
