Ability to follow explicit directions & measure spatial ability...
I was burnt myself, Great lesson learned though.
Prior to completing my Scuba Certification, A lengthy test was administered with the instructor stressing the importance of reading all the questions before beginning the test.
Everyone was feverishly answering the questions in the short time allotted for the test. The last question was, Discard this test and I will meet you at the Pub across the street, I will buy a round for the first five students.
The Prick didn't buy one single round! LOL
