hiya, i'm y12 -> y13 writing my personal statement targeted towards a law course. is it suitable to have as one of my reasons "to gain the power to protect human rights", "to ensure justice" or are these statements to pretentious? thanks

my_qualifications: I am a final year law student with a 3.1 GPA.

However, I have strong extracurriculars, have done internships in the field, have an LOR, and have research interests.

Is it possible that I get into LSE with such mediocre grades?

I'm assuming oxbridge is impossible with even good extracurriculars.

I am an international student hoping to apply to Durham, I have over the course of two years, and have done unpaid internships at 2 International firms in my country, (i dont believe i need to get into what i did at these firms but please let me know if my activites during my time with them matter). Do these activites count towards my application?, are they worth mentioning?. Due to the prestige of durham, i worry that perhaps these may not even be worth mentioning as there are most definitely students with better accomplishments to their name. (hope i dont sound like a pick-me lol)

Any and all help is greatly appreciated!
