English schools / universities / courses ? (Madrid)

Hello,

Are there any courses (or universities) that are completely in English? I just want to look around what's available here. Any websites would be nice.

I don't want to do a knitting class, but serious looking for a career change, but don't know exactly which one yet. I'm a beta person, so I am not looking for any language schools (learning Spanish is already difficult enough and already take lessons 2 a week, but I am still at a basic level)

Hope someone can help me :-)
