Thank you very much for your corrections. I checked my mistakes but I have some more doubts.

1) During our stay in London we were accomodated (we stayed) in a three-star hotel.
2) We had breakfast and dinner at the hotel and we were free to have lunch where we wanted (to).
3) We attended an English summer course in the mornings. The teachers were all experienced and helpful. On the first day the teachers had us do an entry test to assess our knowledge of the language.
4) I was put in a pre-intermediate course. In the afternoons we went on sightseeing tours organized by the school and we had the chance to know the town better.
5) For your final exam you'll have to write a two-page dissertation on a topic dealt with during the school year, which you found (???) particularly interesting.
6) Shall I write my notes in the ring binder? Shall I bring my course book to class next time?
7) Can you wipte the blackboard (off?)?
Can you fetcha piece of chalk?
The flight last two hours and a half (also: two and a half hours). I decided to go to Cork because I was fascinated by its scenery. At the beginning I had to get used to the south Irish accent.
