You don't have to go there. There are many factors to consider, such as whether the course chosen will get you to where you want to go, employment prospects, course content and teaching style.
I was in a similar position last year - I'm currently doing languages at Cambridge but for some time I wasn't entirely sure if it was for me, instead being very tempted by Southampton, particularly over the worry of course content, as my course is very literature heavy compared to Southampton, which I hadn't wanted. Now that I'm here though, I absolutely love everything I'm doing! It's surprising.
Just remember you don't have to make a decision until May!
