What Can I expect studying economics at Cardiff

Hi Guys,
I have applied and have got an unconditional offer to study economics in Cardiff. I have got an unconditional offer even though I have no experience of economics or business at all, furthermore, i last studied mathematics at GCSE! How much study or pre-revision will I have to do to keep up and and be prepared going into the course in September? These are the modules for the course; The Economy: Microeconomics (20 credits)
The Economy: Macroeconomics (20 credits)
Quantitative Methods (20 credits)
Global Financial Services (20 credits)
Finance For Managers (20 credits)
Law and the World of Business (20 credits)
Which out of these modules would I need maths the most and can someone please recommend me some books relating to economics and these modules that I can buy and be prepared for September. Thank you!!
