I got 11 of 15 also. But I disagree with one of their answers - this one:
What name is used to describe a patchwork piece with straight sides and a finished size of 2" x 6"?
a) rectangle
b) bar
c) diamond
Your answer is incorrect. The correct answer is "b". If you answered "rectangle," you aren't alone, because we often use that term to refer to any lengthened square -- I'm guilty of it sometimes. But a true rectangle is always twice as long as it is wide.
However, according to the dictionary:
"rectangle (noun)
a parallelogram with four right angles"
