There are many websites that can provide you with information about student funding. One website you may wish to look at is the Student Money site, brought to you by Hotcourses and UCAS to provide a comprehensive guide to everything you need when planning and organising your student finances. Student Money is made up of four key tools: Search for Funding, Budget Planner, Loan Repayment and Wage Predictor.
The BBC website also has a number of pages dedicated to finance, with a budget calculator as a link from one of the pages.
For alternative funding including support from Charities and Trusts, check out the Prospects Website.
Single parents can find more information on potential sources of funding and charities who may be able to help in cases of hardship via the Gingerbread pages for students.
