What is worth reporting

What cannot be answered

Reporting an item you think is wrong

The most useful format:

Question number: 14 of 30
Type: figural matrix
I answered: C
Marked correct: E
Why I think C also works: the shading rule can be read as running down the columns, which makes C consistent too.

That last line is the part that matters. Knowing why an alternative reading is available is what makes an item fixable.
