  • Assignment 0 Posted Mon. March 30 by Nick Assignment 0 has been posted under the assignments tab.

  • Join CS107ACE! Mon. March 30 by Nick If you're looking for more practice and support as you take CS107, consider joining CS107ACE! ACE is a program that provides extra support to students in the School of Engineering. CS107ACE is a 1-unit companion class for CS107 that provides extra help for CS107 in a small classroom setting. Section will go over lecture content and do practice problems as a class. Sections are an opportunity to ask about anything in the course, and in addition to section, there are CS107ACE-specific office hours twice a week. Besides the extra support, ACE is a great community and a fun addition to CS107! Enrollment is by application, and you can find more information here: click here. Once enrollment decisions are made, students who are accepted will then be given a permission number to enroll on Axess. If you have questions, please email Isabel, the ACE TA (iberny@stanford.edu).
