My whole class is actually doing (all 6 of us) it because our teacher worked as a geophysicist before he started teaching so he decided that our option is going to be this. It sort of makes sense that he is teaching us what he is best at.
We havent actually got any text books yet (we are only just starting the unit and our teacher is starting us off with an assignment on remote sensing)
I think last years class used photo copied notes and im not sure what text book they came from, if i can find out ill post what it came from.
