As a student who did not come from a background in human geography I was worried that I was going to be left confused around certain topics or it would not be relevant to my interests. My advice would be to stay open minded throughout the course as there was always an opportunity to relate the course content back to your own interests and I was never left wondering what was being discussed.
For prospective students I would strongly consider contacting the University and I am sure any similar worries will be diminished. I would also advise students to take any opportunity they can to actively participate in any opportunity given to you. For instance, I was the course representative for MA Childhood, Youth and Social Policy. This allowed me to feed into the running of the course and get feedback from fellow students on how things could be improved.
