CDS course discussion, Apr 2014
[[rightoc}}
This page keeps track of proposed changes to CDS courses that would be implemented in 201415 and future academic years. In the pages below, insertions are marked in blue and deletions are in red and stroked out.
Background: With the establishment of the new CMS PhD program, we are trying to better align the CDS program with the structure of the CMS program and also update our course structure to better serve other options that make use of CDS courses.
