Self-studying Precalculus

<p>I just finished sophomore year and I took Algebra 2. I’m taking Precalculus as a course junior year, and I just want to be prepared for it because it’s going to be really hard, according to everyone who takes it at my school. It’d be nice to “master” the material so it won’t drag me down like Algebra 2 did this year. I’m taking 4 AP classes so I think it’s important that I’m prepared for math.</p>
