I have been reading these forums for a while now but i only signed up recently and I get very confused when reading certain threads because I know nothing about the American school system. When people talk about SATs, college, AP’s, K-12 , etc. I have no idea what people are talking about because all these things mean different things in England. Could someone please post a general guide to the american science and mathematics education system, including things like the age you take certain exams and progress to different schools and links to mathematics and physics course contents and maybe some past exam papers. This would be very helpful to me, I will post one about the English Science and mathematics education system later (it might be a bit of a long post so sorry in advance).
