Hey awesome, where are you hoping to study?
If you've got some free time this summer you might find it valuable to phone up local practices and find out if any of them would be willing to have you in the office for free, for a week or so. You could take the time to learn the basics of some of the computer programs, see some current projects, talk to the architects and just generally get yourself a tiny bit of a headstart! Learning new computer programs whilst under the pressure to do your project is quite a pain, so anything you can learn in advance would help you. I was quite good at Sketchup before I started, which was a big help, just don't over-rely on it as a design tool.
You'll be given a reading list once you get accepted onto a course, two from my 1st year reading list which I constantly promote is "20 Buildings Every Architect Should Understand" and "Analyzing Architecture" by Simon Unwin. They're not too pretentious or confusingly-written, and they lay out of the basic principles of space, walls, how spaces can be manipulated to provide certain atmospheres, etc etc.
When you're at university itself, you might want to get together as a year and try to buy a couple of microwaves and kettles from a shop/final year students. Trust me, when you're rushing for a deadline those microwaves meals will be your best friends, especially if you're able to work in studio 24/7 like we are!
You'll also be given an equipment list, just like Harry Potter
- so there's not much else I could advise.. I'd definitely suggest that you try and grab a good space in studio early on, pin up your name and do a little bit of decorating or something so that people are less likely to kick you out when they all fight for room
I'd spend as much time working in studio as possible instead of in your room, it'll let you spread out more without cluttering your room to hell, plus it's far more sociable. You'll always get some people who shut themselves away for their projects, but studio-workers get far better grades because they can bounce ideas and take inspiration from each other, plus you'll make some great friends. Of course you can make friends with non-architects, but it can get a bit depressing when you have a deadline whilst they're doing sod-all, and then conversely when you have 2/3 exams and they have 7+ and you're not allowed to bother them! Definitely take the time to get to know your flatmates though, it's really nice to get away from architecture at times, and architecture students are famous for only ever talking about their projects with each other!
