got distinctions at uni. Tests per se mean nothing.

Do you see a possible contradiction here?

I scored an IQ of 60 at school. I was thinking too complex around the corner. Same experience I had with a Microsoft "computer driving license" test. I totally failed because I answered based on my knowledge of IT forensic possibilities. E.g. Question: If you delete a file in Windows trash bin: Is the file recoverable? If you want to pass this test you have to give the wrong answer no.

These examples show: We need cascaded test hierarchies:

• classification test
• test with adapted complexity level
