Pretty much everything in the first eight chapters will appear somewhere in a single-variable calculus course. Pay particular attention to trigonometry (chapters 6-8) since calculus involves quite a bit of trig. For example, the unique general solution to the equation where involves trig functions. Also, chapter 5 will come in very handy.

Material in chapters 9-11 probably won't be seen unless you take multi-variable calculus, linear algebra, differential equations, or any other higher-level math.
