Denise Knowles said she was sceptical about the test which involves couples being scored during a video-taped interview on a series of plus and minus points.
She said there is no such thing as perfection in a relationship and that would worry her in any case adding that there are lots of types of questionnaires and tests to see if couples are compatible.
On a positive note she said that it was a good idea because it shows that people are taking the issue of marriage seriously.
So if you're presented with a list of questions along with a bunch of red roses, it might just be the case that your partner is trying to find out if you'd make the perfect match this St Valentine's day.
