Hello everyone! [...] For the essay submission, would it affect my application if the topic of my essay is different [...]

However maybe you want to do something totally new where that would be impossible.

(mine did not match at all!).

Thank you so much for the advice from both of you. It's really helpful :)

I also have a further question about college preference. Which colleges would you recommend if I want to choose one that is near to the law faculty with en-suite accommodation, provides a wide range of activities (e.g. high table dinners, clubs etc) and academic scholarship?
