Mandatory Pre-College Program Activities

CSin3 fundamentals intensive

Students must participate in CSin3 Fundamentals Intensive Saturday Workshops the spring before they start the program. This workshop series will run for 12 weeks starting Saturday, March 13th through Saturday, June 5th. The purpose of this workshop series is to introduce students to cohort program norms and values, prepare them with the math fundamentals needed to succeed in their first year of the program as well as provide computer science exposure.

These workshops are usually hybrid format (in person and online). Students meet with instructors once a week with the exception of holidays. However, all sessions will be held fully online for the Spring of 2021.

Math Intensive work must be completed by the final check-in day (June 5, 2021) in order to continue with the program. Once Math Intensive work is complete we will register students in their Fall 2021 cohort program courses based on the CSin3 Course Pathway. As a reminder students will take all of their classes together throughout the program.

csin3 summer bridge experience

Students who participate in and successfully complete CSin3’s Fundamental Intensive will be officially admitted into the program and in July/August CSin3 will kick off with Summer Bridge Experience, a 4 week, on-campus/online summer experience aimed at building a strong cohort community, introducing you to Computer Science, and laying the foundation for habits and strategies that will ensure student success in the first year of college. During summer bridge students will have the opportunity to interact with engineers from some of our industry partners, which may include Amazon, Apple, DoorDash, Google, Lyft, Quizlet, Slack, Salesforce, Uber, VMWare, etc,. as well as with past graduates from our cohort programs.


Summer 2021 dates are tentatively set for July 19 through August 13, and will most likely be online/virtual with a possibility for in-person the final week. We will announce a detailed schedule by the end of March and post it to the cohort’s shared Google calendar. In the meantime students can plan for 10-25 hours per week the first three weeks and close to 40 hours per week the final week of August 9-13. While we won’t be able to do our usual field trip to a Silicon Valley company during summer bridge this year, we will try our best to get something arranged as soon as Covid restrictions allow for it.
