There are four sets of practice questions available, one of which (on Blackboard only) is a cumulative union of the three practice tests plus both midterm tests:
Scores: 98.6 97.3 95.3 95.3 95.3 95.3 92.6 91.9 91.9 91.9 91.2 89.9 89.9 89.2 89.2 87.2 87.2 86.5 85.8 85.8 84.5 81.8 79.7 79.7 79.7 79.7 79.7 79.7 77.7 75 72.3 72.3 72.3 71.6 70.3 69.6 69.6 69.6 68.2 67.6 67.6 66.9 66.9 65.5 65.5 62.8 62.8 62.2 61.5 61.5 61.5 61.5 60.8 56.1 55.7 54.7 53.4 53.4 52.7 52 51.4 50.7 50 50 45.9 45.3 45.2 44.6 44.6 44.6 43.9 43.9 43.9 42.6 41.2 40.5 39.9 39.9 39.2 38.5 37.8 37.2 34.5 33.8 33.1 31.1 30.4 29.1 28.4 26.4 26.4 24 23.6 23 21.6 15.5 6.8
The first and last questions on every exam were the same. They asked “Did you read all the words of the test instructions at the start of this test?” The test instructions gave the correct answer to both of these questions - two free marks. The answer was located one half inch (1 cm) above the question on the first page of the test; all you had to do was actually read all the words, just as the question asked.
Number of students who got one or both of these questions wrong: 18 (out of 99), which should be impossible because by answering “Yes” to “Did you read all the words”, you would have read the correct answer. Conclusion: People don’t read all the words, and they are willing to lie about it.
find /
): locate
(sometimes named slocate
)[yN]
it means that you must type either y
or n
and if you just push Enter the default will be n
(because the n is UPPER CASE to indicate what the default action will be).
If you’re not actively taking notes in class, why are you here?
