Bad Schools

As Skyman showed me, Public Schools in America seem to be very bad. And I would like to have your opinion, about how bad, and what your experiences are with this.
As to test your own experiences, I have 20 short questions, Please answer the questions for yourself, and DO NOT post them on the Topic.
These are simple tests, and the score is as follows. Every person over 18 should answer the at least 15 questions correctly, without the use of any encyclopedia or anything of the alike. People below or around the age of 12 are allowed to have a maximum of 10 wrong. People who have less then 10 right, should perhaps contact a private school. If you have doubts about the answers mail me.
They are all open questions:

1: What is 4 times 6?

2: How many syllables does the word 'dictionary' have?

3: On what continent are the United states of America situated?

4: Does a poet make Prose or Poetry?
