Background:
The JLPT is not scored on simply “percent correct”, nor it is simply scaled by some amount. They use a fancy algorithm to map each possible combination of correct and incorrect for each question to a number between 0 and 60. Two people with the same raw score can get different scaled scores and vice versa.
There is lots of data available for how many people passed and failed previous years and their scaled scores, but I have not found any data on the raw scores.
Question:
Is there any “average” for what raw score is a passing scaled score? Do the two tend to correlate pretty closely (ie 50% correct means approximately 30/60 points)? Knowing this is necessary for accurately gauging progress with practice tests.
