Yes my wife just did Life skills B1 as Raynaputi says.

We did it because then she wouldn't have to do it again later.

It depends how good your fiancée's english is but my wife passed with no problem.

My wife had to do hers with another candidate who was taking A1. My wife in fact was the only one on that day doing the B1 level. She had to have conversations with another candidate and some conversations with the examiner. Then she did her reading.
