I wouldn't, for several reasons. When renting a house you enter a contract which you can't easily get out of without paying a large sum of money - if you choose to live with someone you're seeing, you can't see the future and know that you'll live happily together for the whole year. Small fights would be exaggerated by the close quarters and less time apart, and you may break up then you'd have to suffer the thought of the sleeping with others in the next room.
Also, at uni you'd have to have heaps of self control not to spend all your time together and instead to get on with your studies sometimes, to end up with a good degree. It'd also possibly reduce the overall length of relationship as you'd find out so much about that person at such a young age, whereas if you didn't live together the excitement and curiosity etc would be extended.
