Could you have passed the 8th grade in 1895?
Shirley Tower, the volunteer librarian for the Smokey Valley Genealogical Society, Salina, Kansas found
an 1895 eighth-grade final exam and posted it on society's website in 1996. Salina Journal published the article on the same
year.
Try the exam here.
Notice that the exam took five hours to complete. There are questions about for whom it was intended. The original exam does
not mention the eighth grade. The document describes itself as being administered orally and for "applicants." This makes
one wonder if the exam was actually for newly graduated teachers. May be eighth grade was the highest qualifying exam to
become a teacher in 1895 in the USA.

how quickly you can find out what is so unusual about it. It looks so plain you would think nothing was wrong with it. In

But if you work at it a bit, you might find out.

three consecutive days without using the words Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday?

eaten in 3 years. Which room is safest for him?
