Reading is definately the place to go to study Geography! Even if you choose to go for either Human or Physical geography, the likelihood is you will choose the other one as your optional modules as most people find them compliment each other really well as well as offering something very different.
My offer last year was 300 points with a B in Geography which i got but i know people who got the same offer but got in on 3 C's and this is where there are over 130 people on the course!
