LSE LLM - timed exams (first experience of sitting timed law exam in 5 years)

Hi, I’m an incoming LLM student at LSE. Last I sat for in-person essay exam was when I was doing my A Levels. I’m actually starting to regret accepting the offer to LSE as I wasn’t aware that I had to sit for timed exams (2 hours for 2 essays if I’m not wrong). Anyway, it’s too late for regrets now.

I would really appreciate if anyone could offer me tips and ways to get through this (ie how do I prep for the exams? How much time I should spend on each essay?) I am really concerned about the exams tbh especially when it’s my first experience of sitting for timed legal essay writing exams…
