Critique my CV for UK Spring Weeks

Hi everyone,

I'll be starting at LSE this September and plan to join a few of the econ and finance societies. I'm prepping my CV for 2027 spring weeks right now and would really appreciate any brutal feedback on the attached draft.

I just had two quick questions about the formatting:

For my chess club experience, I ran out of space and only had my founder role under the leadership section. I ended up merging my professional experience and extracurriculars into a single "Experience & Leadership" section to make it fit. Does this layout actually work or is it frowned upon?

Also, how can I optimize the additional info section at the very bottom? I want it to act as a genuine conversational hook rather than just looking like standard filler. On a related note, if anyone has suggestions for specific technical skills I should spend the next two months learning before term starts, I would love to hear them.

Thanks in advance!
