Ana-sempai failed her placement test in Japanese language comprehension and is given remedial classes. Perhaps JPLT 2 is not all it’s made out to be.
On the other hand, back in the day when I enrolled her into elementary school in America, she failed her English placement test as well, and was sent to a school for little Mexicans. She spoke Spanglish even less than English and the school was pretty much a holding pen for miniature delinquents, so I pulled levers and greased wheels behind the scenes to get her transfered to a normal school ASAP, where she did quite well. Her exams must be affected by Lynette Bishop effect.
 The ESL school was intended for children of all emigrants in theory, but in practice parents who cared for their children’s well-being did everything to avoid it, with the sadly predictable result.
