The year hasn't started yet, so I wouldn't really know!
I highly recommend asking 2nd years and higher for study material! Your free time in med school is already very limited, so it's really important to spend as much of that time productively! It may be a bit daunting at first, but please ask around! Everyone's really nice and generally more than happy to spend time studying with you/ giving you notes!
A lot of medical schools make the connection between 1st and 2nd year students easier by hosting a 'MUMs' programme, like Leeds. You're assigned a family, based off of your interests, and you spend time grabbing lunch and doing activities together. So take advantage of this and get familiar with your upperclassmen!
My main regret in 1st year is spending too much time worrying about non-academic things. As a fresher it's very easy to get pulled into events, some that you wouldn't go to otherwise, out of FOMO. Please just stick to doing things you're comfortable with and partake in activities that you find fun! There's no point going to a billion parties if you're not a party person. Or being part of a society just because your friends are there. University is what you make of it, and it's much better spent when you stay true to yourself!
I've found my work-life balance by scheduling in hobbies before assigning myself study hours. The rookie mistake is to plan your free time around your study. If you do this, you're likely to decide to skip a session at the gym, or miss basketball because you 'don't have enough time'. Treat time scheduled for yourself and your happiness as equally important as those study blocks, and you'll get on fine. Also, please reach out to your tutors if you're struggling! They're there to support you!
