<p>Seeing as I went to a private school in China (Beijing) a few years ago, with a majority of the students being Asians (who don't hold Chinese citizenship), I recall most students being extremely happy to score an 800. Most students were above average, but most had math scores under 700.</p>
<p>And you're comparing two unrelated things. For example, now living in Finland, I can say the matriculation exam for long mathematics (which is a joke, btw) is still more 'difficult' than the SAT; It's just that most students have a lot more time to complete the exam despite it requiring much more knowledge. The SAT tests your reasoning skills and requires that you complete a lot of problems in a short time interval. Do remember that to score an 800, you can only get 1 problem wrong (if I recall correctly). Most people will make stupid mistakes or something similar.</p>
<p>(I'm assuming here that the Korean math 2 test is something like an exam that tests knowledge, not reasoning ability)</p>
<p>Oh, and sorry if this message is a incoherent and difficult to follow along with, I'm feeling a bit tired... :)</p>
