Kijavítanád a hibákat?

I am 16 years old and attend a secondary school. My school is in the city centre. It has 400 students from the age of 15 to 19.The school is more than 300 years old.The current biulding is over 100 years. School time (a teaching is tanítást jelent de szerintem ez a kifejezés jobban illik ide) begins at 8 o'clock. Only ON Fridays we have 6 lessons, ON the other days we have 7 ones. (a lessons-t is írhatod, de ha az ones-t írod akkor nincs szóismétlés. és az one(s) nem órát jelent, de szerintem úgyis tanulni fogsz erről valamikor) My favourite subject is History. We have got a big library from where WE can rent books. After school we can play football ,basketball,voleyball, and take part in some interesting lessons. In the first year we went swimming. It's a great school AND everyone can find friends. After the lessons my friends and I go to somewhere. Our school (a school előtt általában nincs the) sometimes organizes balls and parties. They're very good.
