So.... the sixty million dollar ( = 92.4 million euros) question is....
How is the grade average calculated? Where can I see the maths?
I am starting to think this system is not totally 100% transparent because I have never met a teacher or a rehtori who is capable of explaining it to me. If I understand correctly, only "academic" subjects are included in the calculation (please... which are academic? ...everything except cookery, art and PE??? What about ethics, civics, health etc??) Then some subjects are weighted differently to others.
I sat through a presentation on this about a year ago. The presentation was in Finnish but my SO was there too. So I just sat and smiled in the right places. But when, at the end of the explanation, I asked my husband for a recap, he told me that he hadn't really understood much and neither had anyone else, which was why so many people had been sking questions

It is slowly becoming apparently to me that my son is in a double whammy situation where Finnish Foreign Language (which he is not too good at) has a MUCH higher weighting than A1 English and A2 French which he does quite well in. I am also guessing that a subject called English MotherTongue (which is tagged on to the end of the school report) is not actually included at all in the academic grade average.
The "double" whammy is that although his English is fluent (he is a native speaker), he is getting the same grades (8s and 9s) as Finnish kids I know in Kerava who are "good " at English but way off native speaker level. It seems that the "international" schools are not using the same scale for grading as the Finnish schools. Unfortunately the Grade Average caulculation is the same for all. Unfair!

Now I understand how kids who are barely able to write a coherent sentence in English are able to get into IB lukio, but immigrant kids with fluent English are not....

The other whammy is that if your Finnish Foreign Language (FFL) gets good enough the school transfers you into a Finnish Mother Tongue (FMT) class. When that happens your subject grade takes a serious hit! So we are in the situation where my eldest is getting a 7 for FFL and his younger brother is getting a 6 for FMT even though the younger brother speaks Finnish waaaaay better. Unfair, again

Would be interested to see the algorithms though. Are they published? Anyone else been through all this yet?
