Math E = G-
English C = MVG
Swedish C = IG (lol)
Biology, Chemistry, Physics = IG
Marketing A = G
Tourism = /
IT = MVG
Guess I gotta explain this a little bit.
IG = Bad, this means you failed. You were there and did some work but not enough.
G = Good, I assume this could be an average grade for everyone really.
VG = Very Good, if you want this you have to do some extra work.
MVG = Translated this would be Much Very Good but let's just call it the best, if you want this you have to every possible thing within the course and you have to thoroughly explain everything you do.
+/- = If you get a plus it means you're in between two grades, e.g. G+ would mean you're nearly at a VG. Minus means the same just the other way, i.e. VG- would mean you're almost at a VG but still not at a G.
/ = Nothing, you didn't do anything and you were NEVER there. Worse than failing
Onwards to the courses!
So Math is obviously just math... E stands for the difficulty I guess. There is A-F in almost all courses, A is the easiest and then going upwards.
English is everything related to the English language, reading, writing, spelling, speaking and so on.
Swedish at a later state is more about literature, reading and understanding certain texts and books and so on.
Biology, Chemistry and Physics is all in one, there is a fourth one but I didn't read that.
Marketing is only a course for people going Business and Administration. In Sweden we have different programs you can pick when you start your first year at...a school. I don't know the English word for it but between 16-18 and when you get older you can pretty much do it again if you want too. And one of these 17 programs is Business and Administration.
Tourism is also only a course for people going Business and Administration. The first year you have both of these and the second to third year you get to pick one of them.
IT is...IT stuff. You guys know about that
Long post is long, hope it made some sense
if not, explain please?
