What do you take issue with? The first two are clearly factual. AP tests are limited to a single subject and are 2-3 hours in length.
My comment on grading is also pretty objective, imo. Your AP score is 1-5. And the curve is crazy; when I took AP Physics C E&M I would have gotten a 5 whether I scored 60% or 100%. When reported, though, nobody will know what percentage of the points you scored. OTOH gaokao scores are reported in full.
