I got multiple chuckles out of this collection of kids' incorrect - but plausible - test answers.

Example:
A coin is flipped and then a die is rolled. What is the probability of rolling an odd and then flipping a tail?
A: 0%, because you flipped the coin first.

Some of those answers are brilliant.  

Very funny, Bit. There are some classics in this list.

Hi,
 
I had to take the SAT when I did not know English, and had been in the country only 2 years, and my speaking ability and school work was a joke and very difficult. Only had 2 A's ... in French, because in Brazil I had already taken it for 2 years, and in Geometry/Algebra, where I could deal with numbers and not have to deal with language!
 
The rest was tough!
 I was not able to get into the University because of it. So I finally made it to UCSB in the fall of 1978, and it took me 8 years to be able to improve my English and grades in school because of it. Any course that was writing oriented was a problem. Not to mention the terminology, as things like Physics, Chemistry and Biology were completely out of scope for me!

Yep - my favorite as well!

Absolutely hilarrious!!!!

Several years ago I was teaching freshman general chemistry at a state university along with a group of faculty and graduate students.  There were roughly 800 students in the class so we divided the work ... lecture, recitation, grading, etc.
 
We administered an extra credit quiz during class where the students had to draw a Lewis dot structure.  The quizzes were collected and graded by the graduate students.
 
Up until leaving that position a couple of years ago I had one of the quizzes covertly pinned to a bulletin board my shared office.  The student had drawn a penis.  The students were all in that "18 year old" age bracket so ... it's kinda' like the coffee house ... that kind of childish humor is expected.
 
I saved it NOT because it was a drawing of a penis but, because the graduate student graded it ... and seriously gave the freshman student partial credit.

So, it's not the size of the pen, but how you write with it?
