Information on the MSC in Advanced Computer Science at Oxford

I am currently serving as the Director of the MSC in Advanced Computer Science. For general enquiries, students should write to graduate.admissions@cs.ox.ac.uk
Some basic information on the program can be found here:

The university's description of our MSC in Advanced CS is available on this webpage .

For current students, pointers to various handbooks and regulations can be found here .

Prospective MSC students may want to review information from our virtual open day .

Both current and prospective students may also want to look at example MSC theses. You can find pointers to both recent and older MSC theses here .
