How do Japanese schools do and call post-test corrections work? When I was in school (in Russia), we had lessons dedicated to working out mistakes made during language tests. So on the lesson after the test, every student would receive his corrected test and do some exercises related to his specific mistakes. The teacher would help everyone in turn. Students who did not make any mistakes were free to work on whatever they felt like, I think. I'm not sure anymore if the practice only existed in middle school, or continued through to high school too. I cannot even find a definite name for it in English, maybe something like "corrections". So I'm curious to know how Japanese schoolchildren work on mistakes they made on a language test, and if there is a name for this process.
