Hi, biology friends! I’m Sarah, your other biology professor. I've got a PhD in genetics (I ❤️🧬), and after years of teaching a bunch of different college biology courses, now I’m sharing my tips here on my channel! We’re taking the most frustrating topics and breaking them down - clearing up the tricky parts, and helping you to avoid common exam mistakes.

💡 Content level: Intro College Biology, Advanced High School Biology (AP Biology, IB Biology)...and sometimes more advanced genetics topics because I just can't help it!

📺 Subscribe and check back often for new videos, and more biology content and tips to rock your bio exam!
