The objective is to allow students to have a 40/80, 60/60 or 80/40 split in module choices between Mathematics/Computer Science subject to all students completing at least 20 credits of taught modules from either School. In particular if a student takes the 40 credit year 3 project in computer science they must take an additional 20 credits of taught modules offered by Computer Science with 60 credits offered by Mathematics. If a student takes the 20 credit Year 3 Mathematics project then they can choose to do between 20 and 60 additional credits in Mathematics, and, between 40 and 80 credits from Computer Science.
