Ninth Grade Science Test
This survey has been done before. So it`s not an entirely new concept. But it is a fun little way to see how much you (and your friends) remember from high school freshman science class. I did not reuse any of the questions I`d seen before. I started from scratch. All these questions were developed with the help of my son, who appropriately, is in the 9th grade.
