in contrast to Kasphlam, at my 6th form only 4 people dropped it, 2 because they dropped out from 6th form, and the other 2 were studying world development(taught by the geography dept). and out of about 20 students 6 are doing it at university, and 10 are doing courses related. none of which are me by the way.
=] choose which one you enjoy, i found my geography course enjoyable, not the most demanding, but it made a change from my other science based subjects. also the course was very little maths and science based, most of the maths is pre GCSE and it was only in the coursework or a analytical paper.
