Online Science Courses

We offer numerous science and math prerequisite courses that you can complete fully online from anywhere in the world. We're here to help:

1. Pre-health students interested in taking classes during their "gap" year
2. Post-baccalaureate students seeking to improve their GPA and complete courses while working
3. Undergraduate students looking to complete electives for their major
4. Working professionals interested in enhancing their knowledge for career advancement

You do not need to be registered for a specific certificate or program—simply enroll in a course and you're on your way.

Due to COVID-19, all of our courses are offered online. Pending public health guidance, we will résumé in-person classes.

All of our online courses have been fully approved by the UC Berkeley Academic Senate, so you can expect the same academic rigor as courses offered on the main UC Berkeley campus.

The University of California, Berkeley, is accredited by the Western Association of Schools and Colleges (WASC). UC Berkeley Extension—like all other UC Berkeley schools, colleges, and departments—is accredited by WASC through the University.
