So, I have reason to be returning to school, many years (5+) after my last attendance; and although I took (and passed, barely, after much strife) Calculus 1 and 2 at my previous university, I am very not secure in my knowledge of those topics.
What are some resources for me to self-review that material, outside of an academic framework? I have my old text-book, but I don't recall it being particularly accessible; and more importantly, I'd really like an accelerated approach that assumes prior knowledge of the material. (Books, websites welcome … I'm not a fan of video lecturing or similar, it seems a very slow way to consume information, but if you've a great resource, I suppose I'd take that too :P)
I would definitely check out Khan Academy. Although the website is based around video lecturing, the websites most effective feature are the exercises that are provided on every topic. You get immediate feedback on what you know and don't know. This can save you a lot of time. Then you only watch the lecture you need too. You can also speed the lectures up.
Here is a link to the website: https://www.khanacademy.org/math/algebra2
More importantly, If you had a difficult time at Calculus 5+ years ago, you maybe should start with Algebra II or similar, then work through Trigonometry, Precalculus, then Calculus. Although, this seems like a lot of work, by utilizing Khan Academy's practice exercise feature you may find that you remember the material and are able to spend less time on skills that you already know. This will allow you to identify skills that you are deficient in and allow you to study more effectively.
