I was taught simple linear Algebra in year 11/12 in Australia during early 00's. Stuff like Matrix alegbra, vector multiplication and simple matrix transformations (rotations, shear etc). This was in the advanced math class at a public school. At the time I thought it was pretty poorly taught and I didn't really understand it very well until we covered the same topics in first year of university.
