While I personally have little interest in taking a CEFR test, and don't care about them too much (although the scale is a useful benchmark in absence of /compared to, other scales), there is something I have been wondering about for a long time, given that they seem to have a low pass bar of 50%. So here's the question: Is it possible to pass a C1 barely, i.e. with a 50% score, and yet not be able at the same time to get a top score on the B2 test for the same language? I realize most people who take multiple tests for a language do so over time and thus their results would not be useful for comparison. But my question above assumes someone took both a B2 and C1 test at virtually the same time, i.e. testing the same current state of knowledge.
