Before I came to Royal Holloway I actually knew nothing about my course. The main thing that attracted me (and I think everyone else) to Royal Holloway is the Founders Building. It's such a spectacular setting and really gives you prestige. Looking at other universtities you realise how lucky you are to be studying in such a great place.
Thankfully I love my course as well. I had not studied politics before and not sure of what to expect, but the way the course is designed means you are not signing your life away. In the first year I did a unit in each of the departmental subjects so I could get a feel of what I liked. Now I'm at the end of the second year, which I have enjoyed even more as you are given a lot more choice on focusing on what you're interested in.
The only drawback of studying at Royal Holloway is that it can be expensive at times because you're in a nice area. Moving out of Halls in the seconond year has been quite expensive compared to other friends I've talked to at other unis. But again, you have the benefit of a nice, safe area. The student Union is great and there is always something on every night, so you don't have to venture out and pay the harsh prices.
If you're considering coming to Royal Holloway, I'd say go for it. The atmosphere is great, the location spectacular, and the people very welcoming.
