Most students have access to at least one form of credit, whether it’s a student loan, overdraft, credit card or store card. And increasingly, short-term lenders are targeting students who are running short of funds.
NUS and the money education charity Credit Action have worked together to produce Credit Crunching: a student guide to credit.
This gives you information about all the different types of credit available to students, the pros and cons of each, and details of how they’re usually repaid.
There's also a helpful glossary explaining financial terminology, as well as information about sources of help if you should need them.

Also, take a look at Which student bank account should I choose?
NUS provides this information in good faith and has taken care to make sure it’s accurate. However, student finance issues can be complicated, and rules change frequently. You should contact the advice centre in your students' union, college or university for support if you’re uncertain or need more help.
