@Janwel is correct, I just use the book
@Bobbybob444555 Don’t cut yourself on all that edge dude. And I do try, lol. We don’t have a textbook, just problem sheets.
I have a tutor now, hopefully that will help me out.
Thanks everyone, for your tips, by the way.
Glad you have a tutor!
My favorite website for math besides Khan Academy is Coolmath .com. It color codes all the tutorials and teaches up to pre-calculus. I’m not naturally talented in math, but Coolmath is much easier to understand than all the resources my school gives me. The tutorials are also written in a really optimistic tone, so they can fend off the discouragement and self-loathing for a while. 
I hope this site helps you!
@Bobbybob444555 I’m currently a college Math major (in a week, I’ll officially be a senior!). Your comments are not only not helpful, they are flat out wrong and extremely damaging. Algebra II is not always a “simple” class, for multiple reasons. Even if it were, people have strengths, and not everyone is naturally good with math or has had the same opportunities. I’ve volunteered with a group that does free SAT tutoring for inner city schools; many of the students there struggled with algebra I topics, let alone algebra II. I also went to a high school that is often considered one of the top in the country (STEM magnet school with competitive admission). Our algebra II class covered two solid years worth of math in one and we had multiple units that there was no textbook for; students were often encouraged to repeat the course if they did not get a certain grade (I think it was a B- ) and I knew several that did. And guess what, even though I am great at math (came into college with entire calc sequence done), I got a C+ in physics in high school (it was our regular class but covered AP Physics B curriculum) because I had a terrible teacher. The only reason I got a C+ instead of lower is because I worked hard on my own, bought my own textbook, etc. I did not “quit trying” and it’s offensive that you suggest that is what’s going on with other students. You don’t know others’ situations. Your idea that “if one person can do it, every one can do it” is just flat out wrong, offensive, and quite frankly, extremely ableist. I have a sibling who has dyslexia- they struggled with math because of it despite their intelligence.
@bella22 I think getting a tutor is the right way to go. Watching videos can also be extremely helpful, as you’ve found (Khan academy in particular has good videos). Another option is to buy an algebra II textbook on your own (you can usually find them used pretty cheap) and work out of that. It won’t have all the topics taught in your curriculum, but it will have the more standard ones that’ll be important for future courses.
You also have my sympathies. This one class does not define you. Struggling in it does not necessarily mean you aren’t good at math. Different people are more geared towards different areas of math- I’m much better with the algebras (high school, abstract, linear, etc) than analysis and some other areas. I had to really work my butt off to get Bs in calc based theory classes on probability and stats this year, for example.
