About
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
- Molecular & Cell Biology 102
In partnership with the Departments of Astronomy and Physics, Drop-in support is also available for the following courses:
- Astronomy 7A, 7B
- Astronomy 121
- Astronomy 160
- Astronomy/Physics C161, C162
- Physics 5A, 5B
- Physics 7A, 7B, 7C
- Physics 8A, 8B
- Physics 105
- Physics 110A
- Physics 111A, 111B
- Pysics 112
- Physics 137A
- Python
Please note that service offerings may vary by semester. Biology and Chemistry services are held in Cesár Chávez Student Center. Astronomy and Physics services are held in the locations listed on the schedule.
