Preparing for University
Most universities offer first year students accomodation within halls of residence, although this should be checked carefully as some universities make a guaranteed place a condition of accepting the offer as your "Firm".
Student Finance / Funding
This can be the most complicated and time-consuming aspect of going to university so start early and investigate as many options as possible, especially any bursaries that are available from your "Firm" and "Insurance" choices.
The UK Government site is the starting point for information and applications for student finance, and links through to the specific Student Finance England pages. Meanwhile, the Student Loans Company will administer your loan. An introductory presentation from Student Finance England is available below.
A scholarship can cover a significant proportion of your needs, so find out if you are eligible for one.
For more information, Which have produced a Student Finance Guide (available below) and a Student Budget Planner to help you work out how much you need and how to spend what you've got.
