well, the experience I had in Germany was that there are special Schools for the blind and visually impaired. The groups of students usually consisted of a maximum of 10 people. I was at "Grundschule" first, which could be translated as elementary school or primary school in English I believe. Then, I went to "Gymnasium". I happen to know you have this word in Polish as well in a school sense, from a video of Marta from the "marticore" channel (Highly recommend!)but I don't really get the hang of what it means in Polish. In Germany, basically it's the highest level of secondary education you can get. When I went to Gymnasium, the Blista in Marburg, which is the only one for all blind and visually impaired people living in the German speaking area, which doesn't include just Germany, but also Austria and the german-speaking parts in Switzerland, I also had to get used to living in a boarding school, because two hours by car back and forth every day? No thanks! But yes, the situation is very similar to that in primary school as far as the grouping is concerned. I just love being here, because the people are all really lovely here, which wasn't always the case in primary / elementary school.
There are 13 school years, and I'm in year 11 now. If there were loads of people which were in the same school year, you'd devide the groups, so you get like 7a, 7b etc. From year 1 to 7, I used paper and the eurotype braille writer to do my work, but now, I'm only using a computer, and believe me, that's soooooooo much better! You don't have to carry as much stuff, because it's just data on your hard drive!
So yeah, that's my experience.
