Uni advice

Hey, I've just finished first year, my biggest piece of advice would be not to compare yourself to others on the course. Some people in my year have already done biomed degrees, worked in healthcare for years or started a medical degree in another country, so were obviously more knowledgeable than the rest of us. Also, I know people that partied hard, did very little work and still passed, and others that spent 24/7 in the library and failed the year, so don't feel that you should be studying 24/7 just because others are. How much studying you need to do and the best way to study is very different between people. Also, medical students are usually the best and brightest in their secondary school, bear in mind that you will probably not be top of the year. It can be really hard to adjust to, and lots of medical students end up feeling really stupid because they've com to expect that they will be the best, but make peace with the fact that you don't have to be the best, you just have to pass!
Spend the first term figuring out what works for you. Personally, I like to make notes from the slides before the lecture, then make anki cards in the lecture. Not everyone likes anki, some people like to annotate lecture slides on an ipad/print them out to annotate, I have a friend that uses quizlet instead of anki, so experiment and find what works for you.
Also, in clinical situations get stuck in! On placement, doctors won't always ask you directly 'do you want to practice XYZ with this patient?' so it might be down to you to ask if you can take a history/examine the pt to make the most of your time on placement.
In terms of general life, if you're living in halls it's hard moving away from family and learning how to be independent, so be patient while you figure it out. Learn a few cheap recipes before you move in, and maybe practice food shopping with your parents. The friends you make in freshers' week may still be your friends in 5th year, but they might not be so don't panic if you don't feel like you've found your people, just keep meeting lots of people, join some societies or sports teams and you'll find the right group eventually. If you uni has 'medic parents' in older years then make use of them, mine were great for academic advice and gave me their old essays to read which was really helpful.
Hope this helps, lmk if you have any questions and I'll do my best to answer (bearing in mind I can only speak for my specific medical school).
