The tips that are helpful that Mrs. Ewing told me, who was my algebra 3-4 teacher, was to learn how to graph equations. There are various equations that you will learn in algebra 3-4 so it will be important to remember how to graph them. Some examples of how to graph the equations that you'll learn in algebra 3-4 are at the image on the bottom. An easy way is to learn how to graph an equation is to learn what each degree does to the graph and what each variable does to it like what does square rooting an eqaution do to a graph. Something else you need to know are imaginary numbers which is just "i" in the equation. "i" is just -1 and it will not only help in algebra 3-4 but it will also help you in Pre- Calculus since you do equations involving imaginary numbers.
