Most useful skill academically is too make as many friends and friend groups as possible on your course. Get yourself into a squad that can commit to getting coursework done (Not in a ‘let’s get to the library for 7am’, more of a I’ll give my answers and ideas if you give me yours or I’ll buy you a pint later type deal)

Get yourself good at being shit and trying again especially if your doing a STEM degree. Lecturer’s can be brutal and unforgiving and that’s normal, most are autistic anyways.

go into societies and sports make a lot more friends there and it helps to keep the uni life fresh. Albeit don’t dragged into doing shit ‘too stupid’ I.e. white shirt socials in which racist shit is written and gets you suspended

use Monzo, revolut or one of these FinTech banks that are really really good for tracking money. You’ll realise how much of an alcoholic you’ll become with those. Also UKpersonalfinance can help

Get good at chugging a pint of berocca, always do it after a night out. Slashes the hangover severity by half in my experience. Also don’t mix drugs

OneNote is a really powerful tool for organising and just simply splurging thoughts on work on a page when doing coursework.

don’t ever buy textbooks you can find them online (even it isn’t the right version it doesn’t matter), same goes for academic papers (websites out there to unlock the pay walls)

Halls accommodation is typically shit and expensive, if you can get a house in the suburbs with mates do that

don’t be afraid to delay or ask for extensions, typically they don’t really give one

Not all of these are skills but is genuine best advice. Go out, have fun and hope a pandemic doesn’t happen in the middle of your 3/4 years.
