Hi there! Here's my experience anyway...
1. The first day
Well I lived in Leighton Halls, which is a private accommodation. First day I arrived, and found 2 guys in the living room, somberly playing Xbox, not talking. I thought, jeez, this year's gonna be great(!) I unpacked, went for dinner in the evening with my family, and then tried to make conversation with the two guys who'd already been there a week earlier than everyone else. People in my flat arrived at different times throughout the week but I wasn't stressed as I'd already spent my first year of uni in another city, so i gave it time. I was already safe in the knowledge that I was gonna meet tons of new people! And I also learnt that your ideas and perceptions of people change dramatically throughout the year; as an example, one of the quiet, serious looking guys is now one of my best friends (he's the least serious person I've ever met in my life, up for laugh more than anyone!), I went to visit him in his home country (he's an international student), and the other guy quit after a few months in Preston and we never heard from him again! Funny how things work out, but then that's the best thing about moving away to uni, you learn so much, you go on such a journey with people and make friends for life. As for the first day, seriously, everyone's in the same boat, and you'll wonder why you were ever worried in the first place (if you are about meeting new people) I made so many friends who were really shy and reticient at first, but you literally see them come out of their shell and relax, nobody's out to cause trouble, we all just want to have fun and create a home away from home.
2. The worst thing that happened
Well, nothing's the 'worst' I guess, **** happens but then **** happens everywhere. I guess uni work becomes a struggle at times, it's hard to balance the good times with the work times, as your life can become consumed by all the dramas, people and goings on in your personal life. Mind you, that is half the fun! I think we all went through a stage where we literally had to lock our doors and stay in our rooms for fear of going out clubbing again and not doing another assignment lol.
Another thing was that there was a bit of a divide in our flat between a few of us and one guy in our flat. He moved his girlfriend into our flat, and had his mates round all the time taking over the living room. As cpj1987 said in his post, the dynamics of the first few weeks change. We were all a tight family at first, cooking together, going out etc, but then it changed. It got to the point where management had to sit us down at a meeting and talk things through. Now, depending on what kind of person you are, this could be the 'worst' thing or just another blip in what will probably be a brilliant year. For me, and the type of personality I have, it was a smalll problem (nothing compared to my love life with my boyfriend haha), I made it clear how I felt to their faces and I never felt like I was an intruder in my own home. And so we didn't have much of a problem with one another, though they did eat my food sometimes! But I was a bit too busy having fun to let it ruin anything, but that was me. However my flatmate felt differently, she felt on edge whenever they were around, and was over the moon when they moved out early, which I can completely understand. It's just the way in which you approach things I guess, and we all learn. You'll meet so many other people that rare troublemakers like them will become small fry compared to the amazing people you'll meet. As a side note, the guy, his girlfriend, and his 2 friends never left the house or met any other people. They were from another country and decided to keep to themselves rather than like my other international friends go out and embrace their new life. As a result, they had a miserable time, so again, it's up to you. We tried everything we could to get them out the house, include them in our activities, but they thought they were too cool for school for fun and shenanigans. In the end, they lost out, so be pro-active!
3. Do's and Don'ts
DO make an effort. Thing's won't just happen if you sit on your arse and expect the great uni times to just roll on over to you (like my flatmate, who in the end had a miserable time and wanted to transfer!) Make friends by smiling, approaching people, making an effort in conversation. Even if you're shy and find that hard to do, just join in when invited and stuff, people want to know about you!
DO be open minded. Chances are it's the first time you've moved away from home, meeting people you've never met before, seeing all different types of ways of life/behaviour for the first time, etc, etc. Sometimes it may be strange, or hard to understand, or whatever, but remember everyone else is going through the same thing. You'll find that at the end of the year you'll have changed, but even more miraculous is you'll see how those around you have changed, and sometimes due to your influence! I was so set in my ways at first and thought I knew best, but I've learnt an enormous amount from everyone. cpj1987 mentioned something really important too and that's that thing's change a lot over the course of the year, especially at Christmas. So keep open minded not just at the beginning of the year, but throughout it!
DON'T let uni work slip. Remember why you're at uni in the first place!
DON'T worry. The university has been dealing with thousands of students moving away from home all over the world to them for years and years - there's ALWAYS help. When you're sitting at home thinking about your first year away it is daunting, because the list of all the worries can quickly add up really high, whether it's meeting new people or more practical things like finances. But as long as you have an ounce of responsibilty in you and are not away with the fairies, it'll be fine. Seriously, I have met some of the most unorganised, confused, financially irresponsible people in my life and yet, they pull through! I used to be an over-worrier, about everything, I remember reading through everything on these pages about going away to university, dealing with loans etc before I left. Only to find it was reassuring but I didn't need to! One thing university has taught me is to just ease up; it's good to be responsible and careful, but life can sometimes be a lot easier than you expect.
Phew that was an essay! Hope it was helpful though, I had the best, life changing time with my first year at UCLAN. I've made some amazing friends and as a result have travelled all over England and the world with and to visit them, and I have more travels planned! Good luck with everything!
