My first day of school

Today was my first day of school. We start school at 9am and can go home at 3.39pm. Every day we have four periods (subjects) and every period is 86 minutes. Do not ask why it is so strange...I do not know. From 12.02pm to 12.37 we have lunch break. At the moment I have Math, Foods, ELA (that is English) and Art. And the next semester which will start in February I have my other four classes (Design, Social, Science and PE). We have every class every day. I think that will be really demanding. -.- But the teachers are all really nice! Every teacher has his own room and you go there. They all have their own concepts and the seating plan is different everywhere. Every day before school you can meet your teachers for tutorials. That means that you can ask them concerning the subject and they help you (and there is only you!). And they all use laptops so blackboards do not really exist. The are pretty strict with attendance and punctuality. When you miss at an examen without giving any reason then you get a zero. Every examen has to be written later when you missed it!
Today we only had each period for the time of 30 minutes. So the day was not that long, but every teacher told us the same and what they expect and so on. That was kind of boring. And we had hamburger for lunch (what the called 'Welcome BBQ' :D).
The school is so huge and so confusing. There is the basement, 1st floor, 2nd floor and 3rd floor. And not every room in one floor can be reached by the same stairs. So you have to be careful not to miss the right ones. And then you have to go up and down and through lots of corridors.
The doors of the classrooms are always open (even during the lessons). Each teacher has his/her own room and you have to go there. You get a home room, but I never have there any of my classes...I do not understand this system and I guess I have to get used to it little by little. At the moment I prefer the German school system... Today in the morning we had our assembly and there was only grade 10 today. Tomorrow all grades will come to school. It is all so exciting. I share my locker with a grade 11 girl. And going to school is much more expensive than in Germany.
I am still confused and I am still overtaxed with these impressions!
