Personally, my opinion about the English school UIC Oxford - extremely positive! :)
I was absolutely happy with the choice of the school, the choice of the place of study, and about everything!
Firstly, I think that if there is such an opportunity, it's simply gorgeous to learn the language where it is the official language of the country. After all, it's not just a couple of classes a day, but also practice all day long - in a shop, in a cafe, in a club, on excursions and anywhere else!
It was very nice to live in a family, not a hostel, because I could practice my English with them.
In the school UIC, everything is perfectly organized: after passing the test, all new arrivals are distributed according to the levels. The whole first half of the day is classes. They give wonderful educational materials, which you can keep to yourself and then take them home! I believe that studying at school helped me to advance in my work and remove the language barrier! And of course to see the world, see a wonderful country and have a good rest!
