Pupils at a junior school in Cheshire are seeing double this term, as there are NINE sets of twins.
It can be confusing enough for teachers and kids with just one set, so imagine how hard it is to tell who is who with this many familiar faces.
Thankfully only three sets of the nine are identical, but telling who is who can still be tough.
And things aren't going to get any easier as they get older, as there are 10 sets of twins at the senior school!
