Cardiff and those finance/economics 100% exams? Msc Business/Entrepren and age

Hi
I really like the Business Strategy and entrepreneurship MSc but some modules, for example, entrepreneurial finance, and economics and the business environment have only a 100% written examinations.
I don't have a background in business so it would be very difficult for me to get a pass mark, and I would not like to study everything gain for a summer resit. Is it that hard to pass them?

Lancaster uni has a similar programme called msc in management. They don't say whether they have 100% exams.

Also, I think because the programme is aimed as "graduates" it means that people who have just ended their undergraduate degree are likely to study? I am in my thirties and wonder if all classmates would be so young? I want to fit in.
Thank you for any comments!
