Policy on Working Together Working together the projects (only) is strongly encouraged. (The problem sets should be done individually). You can form groups of no more than 3 students. Students may leave their existing group in the quarter. BUT they cannot join any new group after the end of the second week. In addition, for each group splitting, the group members should tell the reader at least two weeks before the corresponding project/homework deadline. CS122B Notes 01: Introduction
