Just a side note that one is not required to score well on each sectional pass as compared to previous format of JLPT. Previous format requires examine to achieve at least 50% passing grade per section. However the examine MUST pass the overall pass marks and sectional pass marks requirement for each paper.

Meaning if one might be weak in reading and managed to scrape through the sectional pass for language knowledge but very strong in listening and ace the listening section, one can still pass the JLPT exams.
