Program Description

The SLC Science Program supports undergraduates in their pursuit of scientific learning and knowledge at Cal. Our peer-led services are designed to meet students where they are and seek to strengthen their foundation for academic success.    

Program Philosophy

We believe that the ability to engage rigorously in scientific thinking is an essential ingredient for academic and lifelong success. Furthermore, we believe that, with appropriate tools, resources, guidance, and motivation, anyone can thrive in the sciences. To this end, we endeavor to provide Cal students with high-quality, culturally responsive, and equitable services to bolster their confidence and ability to master science coursework. Reflective of the SLC’s overarching mission and approach, we believe that students learning with students promotes community and mastery. We leverage our peer tutors' talents and commitment to service to serve and enrich the science learning communities at Cal and beyond.

Program Formats

We serve students through a variety of access points, from intimate drop-in sessions to small study groups and lecture-size exam reviews. Scroll below for additional information.

Drop-in Services

By actively engaging students in the learning process, drop-in services support Cal undergraduates in enhancing their understanding of science coursework. By collaborating with each other and peer tutors who have successfully completed the class, students clarify concepts, hone their problem-solving skills, and bolster their confidence with the material. We welcome any and all questions related to course lectures and texts, labs, homework problems, and practice exams. In drop-in, students will foster connections not only with science concepts, but with a supportive community in which they can thrive as learners.

Drop-in support is available for the following courses:

✔ Biology 1A, 1AL

✔ Chemistry 1A, 1AL, 3A, 3AL, 3B, 3BL, 32

✔ Physics 8A, 8B

Please note that service offerings may vary by semester.


General service hours during the regular academic year are 10AM-4PM Monday through Friday, beginning the third week of instruction. Hours may vary during Summer Sessions. To view course-specific schedules, please visit our live weekly drop-in schedule.  

Sign Up

Advanced registration is not required! Students are welcome to visit the Science Drop-in Area on the 2nd floor of the César Chávez Student Center anytime during service hours. 

Study Group

Study groups provide an inclusive and problem-based learning environment where students connect with one another to master their science coursework. These weekly sessions shrink lectures down to intimate groups that promote meaningful engagement with the material. Guided by a peer facilitator who has successfully completed the course, students discuss class concepts, collaborate to solve problems, and engage in reflective practice to enhance their understanding of the subject matter. They also develop effective strategies to bolster their science learning toolkit. Students who participate in study group form a support network and deepen their understanding for long-term success in the sciences.

During the regular academic year, study groups are offered for the following courses:

✔ Chemistry 1A, 3A, 3B


Study groups meet weekly for two hours throughout the semester, beginning the third week of instruction. To view session dates and times, please visit our live study group schedule.

Sign Up

To ensure an intimate learning environment where all members can actively engage, each study group accommodates up to 25 students. Thus, advanced registration is required to join. Acceptance is on a first-come, first-served basis and students are encouraged to sign up early in the semester. Students who sign up for a study group that is full may request to be added to the waitlist. If seats become available, waitlisted students will be notified and given the option to join.

Attendance Policy

Please note that although participation in a SLC Science study group is voluntary, students must commit to attending regularly. Members who have two consecutive absences or three total absences will be dropped from study group. Students may not rejoin the same study group from which they were dropped; they must sign up to join or be added to the waitlist for a different group.

Exam Review

Exam reviews are offered at critical points in the semester to support students in strengthening their problem-solving skills and mastery of the course material. Guided by peer facilitators who have succesfully completed the course, students collaborate to solve practice problems and review key concepts. Exam reviews provide an opportunity for students to assess their knowledge and identify gaps in their understanding prior to a midterm or final. Students who attend exam reviews build camaraderie and support one another in strategizing for success.

Exam reviews are offered for the following courses:

✔ Chemistry 1A

✔ Chemistry 3A

✔ Chemistry 3B
