Modified Supplemental Instruction (MSI)

msi-program-iconWhat is MSI?

MSI is out-of-class practice session that provides a space for students to work together on practice problems, go over key concepts as a group, prepare for exams collaboratively, and build community! In MSI, students will learn by participating in activities (yes, activities!), talking to other students, and build the skills they need to be successful in their class. MSI sessions are led by other UCSC undergraduate students (Learning Assistants) who took the class and did well in it.

MSI sessions do not have a weekly commitment (you don’t have to sign-up), students can attend MSI as many times as they want per week. MSI sessions have a max capacity of 15 students. MSI mostly supports gateway courses (the foundational courses students need to declare majors) and core courses (the upper-division courses students need to graduate in their majors) in STEM and some Social Science disciplines.

If you are a faculty or staff member and would like more information about MSI, please contact Sharon Castro (, Nina Gray (, or Ana Martin ( for more information about the services and how LSS can support your course. 


How do I go to MSI? 

Students can view MSI sessions and Zoom links on TutorTrac, LSS’ scheduling system. If your class is supported with MSI, you will be able to view any MSI sessions that are not already full.


Do I need to prepare for MSI?

Your MSI Learning Assistant will have a plan for you! We suggest you bring any books, notes, resources you have for class. Come ready to meet and talk to your classmates!
