Banking Ombudsman Deborah Battell says historically people have found it very hard to talk about money - but we all need to know more about it.
Battell's team deals with hundreds of queries about the banking sector every year and has put together a short quiz based on some of the most common complaints it receives.
"Based on our experience there are an awful lot of us that don't know as much as we need to to manage money effectively or manage our relationships with financial service providers," she said. "We do get caught out."
When Battell was appointed to the role three years ago she was surprised at the number of small things she didn't know herself about the sector and wondered if others were in the same boat.
Now every time the scheme deals with an individual case she tries to learn as much as possible to stop similar disputes arising.
Battell said money was not the be all and end all but when things went wrong they could go very wrong.
"There is as an embarrassment factor for people when something has gone wrong.
It's good for people to realise they are not alone."
