I'm a mate of rudders. Yeah, BDM is very much a mix of lots of stuff. You'll do a TINY bit of web work (and if you do flash, I might be your tutor, haha) - but honestly the web aspect of bdm is very underbaked. You'll do a fair bit of digital composite (digital image stuff.. photoshop yada yada)...
They should be. When I finished bdm they were just about to launch a double degree in comp sci + bdm. Don't ask me how that unholy combination would work.. chalk and cheese honestly
