How would you feel about going to school six days a week? That's what Bartosz does - and he loves it.
Bartosz, 11, moved to England from Poland a year ago. He started going to an English school, even though he didn't speak English at the time!
He also signed up to Polish school on Saturday, where he learns in Polish.
Since 2004, when it became easier for Polish people to live and work in the UK, more than half a million Poles have quit Poland to come to live here.
Helen went to meet Bartosz, to find out how he's been getting on.
At English school, Bartosz studies maths, science, PE and all the usual things in English.
Even though his accent made him stick out at first, Bartosz isn't alone.
He'd like to stay in England
The best thing about England is that you get less homework so he can play with his mates more
The main thing he notices is that the houses here are different
He might like to become a doctor one day
There's another Polish girl in his class and the number of Polish children at his school has almost doubled in the past year.
There are more than 500 children at his school, and 38 of them are Polish.
And Polish school on Saturdays is a chance for Bartosz to hang around with more Polish-speaking children, and it means he can learn more about the place he comes from.
There are about 66 spread across the UK, and a lot of them have been running for 50 years.
At first, they were set up to teach the children of Polish families who were born in the UK, but that's changed recently.
Over the past few years the majority of children at Polish schools are born in Poland but move to the UK.
