In the first period I studied physics, chemistry, English and Finnish. Because I am a senior I can onky have 4 courses because I've done most of the obligatory courses and now I'm mainly studying the subjects that I'm going to do the matriculation examinations in.
The autumn examinations are often at the beginning of September which means that the first perion is still ongoing.
I did the matriculation examinations in English and health education, now I'm waiting to find out my final results. I'll do a separate post about the matriculation examinations so if you're interested you can read it or then post a question in the comments.
After the autumn matriculation examinations the seniors have a special day called "100 aamua" which is when seniors have 100 days of school left they come to school wearing their PJs. I think this is a fun tradition in Finnish upper secondary schools.
