This will happen more quickly if you learn a few life skills before you start at university, such as being able to boil an egg, read a bank statement and put the right amount of bleach down a toilet.
One of the first things you should do when you arrive on campus is to walk around and identify all the buildings relevant to you before you have to find them in the five minutes to spare after realising your alarm failed to go off. Join the campus tour, library tour, even the tourist tour so that not only do you know where lectures are, you can also feel a full part of your new community.
You also need to join something - a society, seminar, bus queue - as soon as possible so you can start making friends. It is much harder to join things later in the term, so resist the temptation to appear mysteriously self-contained.
