Important Topics from Algebra II in PreCalculus

I’m currently finished with my Freshman year and I’ve been teaching myself Algebra II over the summer with the aim of skipping the class next school year. Now that I’m most of the way done, I’m confused as to which direction I should take my studying. Moreover, I’m wanting to know which topics from Algebra II appear most commonly in Pre-Calculus. Which topics do you wish you were prepared for before taking Pre-Calc?

Everything trigonometry. I would also definitely review solving and graphing quadratics. There’s also these things (I can’t remember what they’re officially called) where you modify the basic equations for parabolas, hyperbolas, etc and it shifts and/or stretches the graph in a certain way. Learn that. It makes graphing so much easier.

Also, learn geometric and algebraic sequences because they show up also.

Lots of the Algebraic principles carry over, especially factoring, and simplification. There will be lots of trigonometry and graphing. But honestly, you can just google what is taught in Pre-calculus to get your answer

My friends have told me that when they took Algebra 2, they learned the unit circle. Not sure if that’s the case with you. I was ahead in math, so I learned it in precalc before our district changed the curriculum. I’ve taken precalc honors, calc honors, and AP calc AB, and it’s something you definitely have to know for those classes. I would recommend printing out maybe like 10 copies of a blank unit circle and trying to fill them out by memory till you have them down pat. Good luck!

“Precalc” is a VERY vague term-- it’s like “Geography.” What’s taught in my school may not match what’s taught in yours.

I would take a look at some NY State Regents Exams. If you can successfully take a few old Algebra II & Trig Regents, you should be on track for whatever your school teaches in Precalc.

Oh, and the shapes that @ski_racer was referring to are called “Conics.” The shifts and stretches are called “Transformations.”

Thanks for the feedback everyone (I am the OP),

To provide some more insight as to what I’m learning over the summer, I’ll post a quick list of the chapters which I have covered, I plan to cover, or will be skipping over. Note that I will also put a check mark over chapters I’ve finished and an “X” over those I have not.

Glencoe/McGrawHill Algebra II:
